Thank you for your advice. I've got lots of materials except I'll have to get some more hardware cloth. I'm not sure how big or tall I should make it for 12 so that they don't outgrow it before they are ready.
So I'm trying to figure out what to do with my 12 babies. They are about three weeks old. They have quickly outgrown my wading pool brooding pen, plus they want to fly so they bang their heads on the chicken wire lid. Usually my chickens are ready to move to a secure pen outside by the time...
