I never raised chicks before and I just purchased 10 pullets (5 barred rocks/5 rhode island reds) I them in a medium rectangular bin with a water bucket, there food and a heating lamp. I think they are 2 weeks old, and I just got them wednesday and where we have them the do fly to the edge of the bin, and yesterday a few of them got out and flew back in. We are in the process of building their coop before its time for them to go outside. My questions are: when do I let them outside? now that we are in the fall how will they do when it gets cold or even snow? How will i know if there feather got thicker? Do they grow fast, where it is visible? I bought a 5lb feed from the store, is there an organic feed that I can give them? What a fruits/vegetable scraps? In the winter do their coop need to be insulated or what can I do to be sure that they are warm, when its cold/snow?
