I moved my 6 week old Brahma chicks out into a miniature coop yesterday. They are all feathered out except for their heads. Temperatures are going to be nice for the next 5 days, however I am noticing that after that, although day temperatures are in the 60s, night temperatures will fall to 45-47 degrees. Do you think they will be able to withstand? I have no way of getting any heat lamps out into their coop and dear wife doesn't want to hear anything about bringing them back in.
They'll be fine - mine went out at 5 weeks and were in temps below freezing about a week later when we got a sudden cold snap and snow storm.
