Our chicks are over a month old, really. They are from a farm store, purchased a month ago today. The coop and attached run is nearly complete, which is good because after they have been outside and get stuck back in the brooder, they get pecky. Between the rain and unseasonal cool weather here in Washington State, I sure am ready to be outside, myself. All four original girls seem healthy and usually happy. Thanks for all your tips and shared experience!
