Hi there! I currently have five 5 week old chicks, 2 buff orpingtons and 3 cochins. The buffs are fully feathered now and the cochins are almost there. I live in FL and normally would be moving them out of the house and to the coop right about now. However, our weather has been weird lately and we have not had very warm days (for FL). Lately the highs have been high 60's and at night it's been getting into the 40's and 50's. I'm afraid it's still too cold for them, at least at night, but wanted advise. I love them to death, but I'm ready for them to be outside!
