I have 5 chicken's, 1 has had a long list of health concerns but seems to be happy doing her chicky thing so we have resisted culling her. While our girls have a large brooder box they are QUICKLY out growing it... and they complain LOUDLY about the cramped quarters.... Our girls are 2 months and some change old and the temps are dropping into the low 40's at night here. How soon can we move them permanently to their new coop and run? What should the temps be? We want them to be comfy and not freezing cold....
