Well,usually mine will open their eyes in between 2 to 3 weeks.
After that,they will be VERY active in the cage, running around.
After around 25 days, should be ready to let go.

I'm thinking of letting go 1 of my WW pearl female as she haven't give birth until now.

buy formulated milk to feed the babies if u dunwan mom to feed it. But it is very troublesome coz u need to feed them every few hours.. What brand bedding u use?

Copy and paste from website.

At 10 days or sooner they will begin crawling out of the nest. Their eyes and ears are not open yet, but they follow their sense of smell to find food. When they do this, you may want to begin feeding enough greens and fruits for them also, but chop them up in very small pieces to make it easier for them. If they don’t have that moist food and only eat their mother's dry food, they will dry up her milk supply, especially with a very large litter. They need the moisture from the fruits and vegetables as well as her milk. You will also want to make sure that the water bottle is low enough for them to reach it now.

Pretty soon, the babies will become rounder and fuzzier, and look more like hamsters. They can be weaned as early as 18 days, but it is better to keep them with the mother for 28-30 days. Males can be taken away a little sooner. These babies are 3 weeks old (21 days), and this is when I usually separate the males from the mother and the rest of the litter.
Just to let u know , i separated my male babies from the mother at 20 days old. Females at 23 days old. But it is winter white.  I think u can separate ur babies from mom already. Have they opened their eyes yet?

Im sorry for u loss . In a litter , u have to know that not all 100% of the babies will survive. Just like my hamster litter ,5 out of 7 of them survived. I am no expert in syrian hamsters , but whenever i go to pet shops , the eyes of the babies will mostly be closed. Dont worry , my first time having hamster babies , the mother eat all of them  . I was 10 year old that time , so blur about hamster.

About the greens and fruits , its okay if u give in small amount , not everyday . Its like we cant eat durian everyday right xD.

I guess u can feed apple. Not sure about cantaloupe or honey dew . I fed mine with apple. U can give them some carrots too , or u can take bread , soak abit milk and give ur hammie to eat.

Perhaps ur hammie was fighting with each other. Is your box too small? I heard that syrians are solitary and prefer to go solo.
