My son-in-law helped me build a coop then moved to another state. I can't let this work of art sit empty and have a friend who is wanting rid of a bunch of his 2-3 year old chickens. They recently quit laying but the weather here turned cold. I've heard that if I heat the coop they might start producing again. Coop is 5'x5' and I'll mount a 2x4 roost a couple feet off the ground and the nesting box 18" off the ground today. I've thought of adding some foamboard insulation as the coop is built of 2x4's and tin siding. What do I do when I pick up the chickens? I can't very well put them in the cab of the truck with me; do I stick them in a gunny sack for the 20 minute relocation drive? After I get them here do I stick them in the coop for a couple of days and then let them out to range? Presently they reside in an open barn so these are gals who are rather independent.
