We have had our store bought chickens a year this Spring. Only ONE out of 7 hens have tried to to hatch eggs. She has had two chicks and is laying on three eggs still, two are duds for sure, maybe another will hatch, feels heavy. I have her in the coop separated from the others with her clutch. Since this brooding, this hen and none of the other hens, have laid ANY eggs in the last two weeks! Could this change in the chicken coop be the cause? Also, Gru, the rooster has mated with several of the hens, however the brooding hen is the only one he hasn't plucked into ugliness! Maybe his favorite? IDK?
