I have 24 pullets and my run is 2000 sq ft. Coop is 8 x 16. I have grass there, but now that fall is well underway, the crab grass is dying off. I recently fenced 1/3 of the pen off and cultivated and seeded, being that it was largely bare after building the coop, etc. Ky 31 fescue and creeping red fescue as there is some shade there. It is coming in like gangbusters and I have already fed it only a week after seeding it. Am wondering if I need to reduce my flock say, by 1/3 to keep the grass there in season once the new part has grown in? I do not need 24 chooks for sure, so am wondering about all of this. I have been told that no grass will be there eventually, no matter what. Is that right? Would like to see grass there always for fresh live greens and calcium for the chooks, plus ground bugs like cover and will not enter a bare pen from cover.
