I thought it would be ok to integrate and they seem to be doing fine, but eggs are def smaller. The little ones have been on starter/grower crumbles and hens on layer pellets and they seem to be eating more of each others' feed than their own. I have oyster shell out daily, too, but my eggs have gotten quite a bit smaller in the last two weeks. Should I go back to keeping them separated and only free ranging together? It's not difficult, I just thought it was time..maybe too soon??
