I am getting ready to order my first batch of shicks and need to know a few things first.. 1.How long will they be in the brooder before I can take them outside to the coop. 2.I figure by the time they are ready to be pu tin the coop winter will be knocking and I have no heat in my coop, what do i do? 3. I am ordering a mix of 25 barred rock and RIR's.. I know they have to feather out before going out into the cold but what does one do with them when they get almost ready as far as caging? Thank you in advance!
