I like to use a red light bulb because it doesn't interfere with their sleeping some use blue. white light will disrupt their sleeping. 6 Pekins are going to grow so fast your going to be amazed.Oh yeah I was worried about them getting out so I stood there the whole time. I will raise the lamp a bit to get that temp down to around 85 or so. Or maybe I'll go grab a lesser wattage bulb. I have a 250 now. Maybe a 100 or 150 would work better to achieve that temp.
I plan on starting that garage pen for them tomorrow so soon they will have lots of room to play. At least until they grow some more haha
