Looking at your picture I'm noticing several things...
1) The lamp is low enough that none of the chicks are under it.
2) All chicks are in a semi-circle around the lamp, which I think means that it's too cold in your room.
3) All food and water dishes are in the cold zone.
Can you add another lamp and raise the one that's in there and move their food and water closer to the lamps?
This is where one group was before I moved them just after I changed the water.
I have another 100w bulb I can add tonight. I hung it last night, but was too worried there would not be anywhere for one that wants to be cooler.
