Thanks to everyone for the replies.
We live right on the gulf coast, so it's pretty warm, hot in summer, so I built a 10 by 5 ft. hen house. It only freezes 2 - 4 times/year, so the top 2-3 ft. is just hardware cloth. It can cover that with plywood or just tack up clear plastic in winter...
My twelve black Australop hens are now 6 weeks old, coop is almost finished. How and when do I transition them to the new hen house?
Do I just move them to the hen house? How old? Is eight weeks good?
I thought I might shut them in the hen house for a week, to get them used to being in...
