3 acres. The house & garage are on 1 1/2 acres fenced with chain link. The coop is on the other 1 1/2 acres. It's somewhat fenced-broke and rotten. We have new rolls of wire fence to put up back there, just need time, muscles, energy, and not so hot weather!
As of now, we let the chickens out to free range about 10-11am. All chickens run immediately to the yard. Hardly any stay in the back. Weeds, brush too thick, tall etc. I'll try to get pics to explain better.
All chicken pens will be in the middle of the property. Front part of the back if that makes sense.
