I've been reading and reading but I cannot find the answer to my satisfaction: What age can you move your chicks to coop if the nights are 50°-55°F and the days are 70-80F? I live in Houston and there is still a chance it could possibly get down to 40 a couple more times this year but very unlikely. The almanac says our danger of frost is past Feb 24. I could put a reptiile nighttime heat lamp in the coop If it gets too chilly some night, or bring the chicks in. I have a 5 week old Ameuricana and 6+ week old RIR and Ameraucana. I also have 2 tiny baby chicks I will need to know this answer for them too soon. The weather will be even warmer in a month when I'm starting to wonder with them. I would love to hear from others in warm climates. What do y'all do in Florida and Hawaii, for example??? I used to live in Oregon when I had chickens before so I knew the answer for that climate.
