they don't seem inclined to peck so far, but they only just hatched today -- and i like the idea of keeping the broody & her kids in the exclusion pen (inside the run) for a week, my only concern is about moving the one who's already in there. but i suppose the only way to find out is to try! at least she'll be going back into the preferred nesting boxes, the ones she was barging into earlier.Moving broodies on eggs sometimes works, sometimes dosen't. can you put her in a box and wire it off for a few days so she can't leave( with food and water) ? 1 week of isolation is good for mamma and babies. they will still be small then, but they will be fast! It all depends on if your hens want to peck at babies or not, some do some don't. My non broodie hens don't spend much time in the coop, so its easy for me. but the incredible rotating broodie box sounds like a workable plan.
OR, i suppose, the other option would be to buy a second exclusion pen tomorrow, and put broody #1 and her chicks into that one for now -- and just leave the one that's settled alone?
thanks for helping me work this out!
