hi! so, we've got our first 6 chicks and 6 more hatching any minute. I have the brooder going well, a smallish second hand coop/hutch that I intend to use as a transitional space, and we are finalizing our plans for the big coop, which we intend to make big enough to house 20+ hens. all my chickens will be mid size to large, based on breeds, so I'm trying to figure out when to move them from what to what. I told my husband he has 6-8 weeks tops for the big coop and run to be finished but I'm wondering how to go about the switch. I'm in South Texas, so pretty mild weather right now compared to most, but some cold nights still. I've got the brooder in the garage and the coop outside. At what age should I move them from the brooder, like 4-5 weeks? The coop I have would be far too small for all 12 chickens full grown, but I figured as that transition to outside and wait for the big coop it should be sufficient. It's about 16 sq ft, and I'm going to add a couple of roosting bars across in to help "pretend" there is more space. is there anything I need to know or plan for? I don't intend on keeping any cockerels, these are all straight run, so I'm sure our number will go down by a couple. thanks for any advice you can give!
