My boyfriend has been building a coop for our chicks, he is just about done, he has to hook up the last light and hang the feeder and waterer, but my question is how old should the chicks be, before we put them outside in the coop, I live in Western New York, so the weather has been pretty funky lately, yesterday it was cold and rainy and today its in the mid 70s and humid. My chicks were a week old when I got them, on April 28th, so now theyre four weeks old. I dont want to put them out there too soon, so I was just wondering. Thanks.
