I have 29 Chicks split between RIR's and Barred Rockes, as well as two silkies. The silkies are about 8 weeks old i believe, and the others were all hatched the last week of January. I live in MA and during the day, our normal weather temps are between 20-35 degrees, at night usually in the teens/ singles.....but as we are starting to come to spring i believe it wont get to much colder. I currently have them in an extension of our home that is not heated but stays around 30-40 degrees however, i have the chicks all in a brooder with a heat lamp that i decided to shut off today because i just dont think they need it anymore. They are getting to small for this and are going to need some more room soon, but i as well want to just get them adapted to the weather. When do you think i can move them into there coop outside, do you think they still are to young?
