@unknownhammie: does it look like the eyes are stuck together a little? Maybe it's eye infection. Not sure what the symptoms are but hamsters are usually energetic when awake mar.
@mecool: boiled egg is protein source. You can give daily but make sure your mealie reduce number lo.

They're quite small for 1 month. And their fur don't look dense. They're not inbred, are they?
You don't have to take care of them 24/7 wan. In the morning when you wake up, give fresh smoothie (enough to tahan until evening. ), give a lot of fresh vege and fruit, make sure their water bottle and dry food got a lot. You can buy LC vit syrup to increase their appetite.
At night come back, give another bowl of fresh smoothie, fresh vege. Give mealies also lo.
You adjust adjust a bit. Giive them a little bit more than they usually eat so that the hammies still have food if they decide they wanna eat more. Their growing period is very important to determine their health and size in future.
