I left nesting planks out of the area above the void, so you waste the ceiling space on 1st floor and 2nd floor.

I've seem some other people come up with some mechanism to harvest that space. To me it is not worth it risking a fall from those places I just left them empty. Besides, if your 3 storey BH is really full house, that little space won't matter anymore.

If you compare this to your straight down design, actually you're only wasting 1 more void section. If your void is 10'x10' you have 100sq.ft less space, not a big deal imo.

Also think/check properly if rubber plantation. Personally have some reservation for rubber land.

Your design is more or less similar to mine and I regretted my design because of the staircase insides the building.

send me your google sketch up files, easier for me to describe by changing the the drawing.

Do not have walkway at far end of the roving room as it acts as a barrier to the new incoming birds. The air well should not have any obstructions.

In out holes should be closer to the corners so that when a bird comes in it will not overlook an abyss.

70' x 23' is the size of bh, right?

from civil practice point 80' x 20' will be economical . all column apart is 16' .

after deduct staircase 4 feet n walkway 3 feet, left 13'. so opening 13'x 16' still acceptable
hence staircase r in a room, u can create a glass opening at the centre well.

in these case no additional  beam r required n it will save cost on the rc work.

Don't think it got to do with the acid. More like the amount rotten fruits. IMO, sawit generates more insects than rubber. Also for rubber, obstruction to flying path the main issue. Got to think whether they can circulate around ur bh, more playing ground for them sort of. Anyway, just my guess.

As D day for the industry is getting nearer but still many owners blasting their sound as if they have the right to do so without consideration of others feeling.

Spare some sympathy to those who are going to fight your battle

It's easier said than done but if you are the one that help to negotiate the safe passage for the good guys and what's then, the bad ones will get to you cos' the blame on you that they are not allow to stay @ town. then what???? Will the ones that you help to allow to remain @ town help come to your defense if these really mad and unhappy owners are going for your hide for the bad ones aren't going to admit that they cause their own destruction and that  you are the culprit that cause their BHs being not allow @ town....they aren't going to think that you have save those who are cooperating and should be allow to stay and convincw the authorities  that action is needed to be taken only against the bad ones.

I won't want to be the one to try to save those who follow the recommendations and make peace with the rest of the population cos it shall be my hide at state. My own home being disturbed by the BHs sound pollution an many occasions  and even with my close connection with the Association manage to solve the problem for a month but just one month and then what?????? Those A**H*** have no brains and they don't know that by doing so, we are helping them and to ensure them of a chance to remain @ town and they think that it's their Right to remain or all BHs can go to hell (demolished) together!!!!

Only if I be given a legalized torch to burn (007 license) and I will burn down their BHs if they repeat the disturbance after warning so that we will have better chances and leverage in negotiating a better deal with the authorities. Maybe, self control by the Association, lower fees and non interference from the authorities is my agenda. 

No offense to anyone in particular but just to speak for all even those who object to the industry. We must appreciate their understanding of our industry but we also must respect their rights to good living!!

Lesson learned .... DO NOT MESS WITH ENTRANCE HOLE
My attempt at using nail carpet to repel pigeons might have scared the swiftlets away.

There were pigeons standing on the dog kennel ledge and dropping their poop into the staircase airwell back in January to March.
The months where I used nail carpet matches the decline of swiftlet dropping growth.
Used in middle of March, removed it in late May. June was the monsoon season but I failed to take advantage of the opportunity.
Don't have any photo of it.

I won't be going but from the description of the conference is sounds like an educational conf, probably gonna discuss long term prospects and things like that than ACTUAL swftlet farming itself.

Yet they are still charging $800 per person?

From what I heard, the formal course attended cannot be use as the V-dept comes up with a new 1GP course and to get the license to operate, one must has the new 1GP certificate; again another fees to pay to the V-Department and the course is similar to the formal course provided by the V-Dept, I can predict.

Oyes, the 1GP booklet will be sold for Rm15 and can be obtain @ V-Dept thru internet and Dr. F stressed that no one should photostat the booklet as it's copyrighted and copying is a serious offence.......... copyright OK but why don't allow Malaysians in the buz to copy if cannot get one copy which The authorities want all in the buz to know and follow; let all copy and learn if that's what the Govt. wants.

Again that's my personal opinion only.

As Dr. Fadzilah mentioned @ K. Trg on too many researches have been done on the same thing on swiftlets, and a  waste of govt fund and Uni must first check if other Uni is doing the same research as there are really so many studies can be done on swiftlets and the industry.
  that the birds do sometime alternate their parenting while the other one goes in search of food far away or could it be that swiftlets arent mono but polygamy in nature...hahaha.....anyone got the answer?

Well, just my observation to share.

On headline news, I think  this is the biggest step in the right direction so far to fight for our
existence. Black sheeps under the guise of Made-in-Malaysia to export fake/blood bird nest
to China for more dollars than sense. Our govt should push for the 30ppm of the nitrate
contents as agreeable level and in order to reduce nitrate content at source, if using EM is
one good way, by all means make it compulsory for all farms.   

Why should sodium Nitrate and sodium Nitrite be an issue ?


It is obvious that someone is trying to manipulate the market. 

So, why are the Associations not actively correcting this problem ?

heard that they are implementing RFID where each time u enter the farm, u need to accompany by an officer to enter the farm, and when harvest finish u placed the harvesting in boxes n seal with the RFID sticker then send to approved factory (10 factories that already get their licences fr VET), sell to them at market price. and this is to ensure the quality of bird's nest woh...

officer need to follow u enter the farm as they need to scan the gps tracker installed (u have to buy from them loh)  in your farm n to record the date n place those nests harvested from which farm... then only they have records woh..
