Hello, i am trying to figure out why my leghorns are not laying eggs yet. I have heard that leghorns lay early and were bred for laying early but I m not sure why my chickens have not layed eggs yet. Can someone help me? I give them water every day the required food, I let them out at 8:00 every morning and put them away at 8:00 and occasionally put a lamp in there. Also, I did add 2 new older birds to there flock about a month ago. Could this mess up there egg laying? I also have a duck, i am not sure if that is a problem, she does seem a little bossy. Anyone have any ideas? Thank you!
