Hi! I have 2 Cornish cross "chicks" that are about 3 weeks old. They are huge compared to the rest of my 2-3 week old chicks (a mix of Tractor Supply dual purpose breeds and packing peanuts from a friend's Ideal order). The Cornish Crosses are about 10 times bigger than everyone else and they are getting pecked and bloodied by the littlest chicks of the bunch. I'd like to put them outside, but there is still snow on the ground and they'd be in the chicken tractor. What are their chances for survival if I put them out now? I live in PA and the 10 day forecast is showing that the highs are mostly going to be in the 40s.
