What is the normal time frame for the chicks to stay in the brooder? I just built a 2'x4' brooder and made it taller just incase. I have yet to start coop construction and would like to know how much time I have. I have not picked up any chicks but found some barred rocks at a local feed store that I would love to pick up. I know wait until they are feathered out but how long does thatt take? Also temps around here have been in the low 40s to lower 30s at times still. The weather has just been wierd this year. Thanks!
