Hey this usually isnt a problem for me, but with it being cold(I live in Pa). What is the soonest you all think I can get away with putting them outside. The nights are around freezing and we dont heat the coops. the oldest chicks are about 6 weeks, the youngest about 3. I ask because they are picking on each other a bit. I had to separate a few to treat injuries from haveing neck feathers ripped out then picked at till they were raw. I cant give them any more room inside. ATM they are in a 6'X4' enclosure. there are 20 in there. any help is great. As I said usually this isnt an issue because we do this in spring/early summer so temp isnt really a conscern.
