If that was my BH i would just do something like this. Have the roof top opening's entrance on other side instead. This way it is easier to control light and less wastage.

And personally I don't like these so called VIP rooms, never worked for this. Just my humble opinion.

If New BH, FLIGHT not Light.

One Suggestion: Sliding doors.

thanks good advice. even my bh only 107 nest 2 years......

To newbies, consider buying established bh when price are lower now instead of building new one, do make sure it still has potential for further growth. Besides, it is one way to help those who might be tight on cash flow.

what is the current price for BN? isnt still rm2.5-rm2.8k?

Reality check, CNY is coming in 1 month's time. If there's such a huge demand we would have already seen price increase some time ago.
Mind you BN is not like vegetables you harvest them from the field and can send straight to customers. BN needs to be cleaned, packed and shipped overseas.

Therefore if the retailers see a surge in demand and the processors get orders they would have already started stocking up, not in a few weeks time. Hence my conclusion is this year's demand for BN is basically gone, can only hope for clearing up of the red nest mess next year and hopefully Chinese start consuming BN again.

My opinion to share.

1. Cultivation of fruit flies and releasing them at the BH are only because not many birds visit your BH and your intention is to draw more  birds  attention to your BH.

2. Adding fake nests is to encourage birds to quicken nest building in area which normally is empty of nests and never in area already with nests. This is to encourage birds to lay eggs in the fake nests (with little additional saliva) esp. for the young birds whose nest building skill isn't good at all and thus helping to fasten the process of nest building and increment of nests.

3. Remember that only old birds will remain faithful to your BH and not the new fledged ones and they will leave your BH leaving half built up nests or even after building their first nests in your BH and what you need is to ensure that they do lay eggs and nurse their chicks to fledging. Only after this full cycle can you call these birds your faithful birds and not before then.

When I was building my latest BH, because it had lots of tall trees around my agri land I had to pay to local kampong folks to chop down some of those huge trees.

However due to logistic concerns so just left those trees as it is and let them rot. Occasionally I will tell the folks to try and help me burn the tree trunks off bit by bit but since it is too huge they are basically still around. Lately I noticed these rotting wood are actually breeding a lot of insects especially after rain you see all those termites flying around and only around these rotting wood and  the number of swiftlets 'cari makan' around my agri land is unbelievable.

So there you go, maybe this is easier than breeding fruit flies or what not (somemore might bring disaster to nearby farmers). Just chop off some nearby trees, stack them up and over time they will rot and attract insects.
