My daughter got two chicks from her Vo-Ag teacher at the end of the semester (another class raised them). They are fully feathered but I'm not sure of the exact age. We have raised chicks for years - but only in spring! - and I can't figure out what to do about heat. We are in Southern New England (currently a cold snap). They were housed in the classroom before we got them. They are now in an outdoor mini-coop (separate from the rest of the flock) with a heat lamp on 24/7. The heat lamp is keeping the whole coop above freezing (the water in the far corner has not had ice), but how do I go about transitioning them to cooler temps? I've never done this when it's quite so cold before. I have been letting them out into their run here and there, but I could also use some guidance on that. Thanks in advance!
