My boyfriend and I got seven hens two weeks ago. They are from three different farms. Three are about 18 weeks. Four are about 1 year. They have a nice coop, layer scratch, oyster shell, grit, they free range, they are friendly to me and with eachother. In two weeks, we have received about one egg a day. We think it is from the RIR. Her comb is red and she seems the most "in touch" with the whole chicken stuff. We are at a loss as to why the other three adult hens aren't doing anything. They coo and talk, they are alert and have a routine. We are so excited for eggs. Any advice?
