My hens haven't produced any eggs either. My male is still breeding and still has a full train, hoping I'll get at least one to stick in the incubator.
No hidden eggs from my hen,
i am outside just about all day and she is always around the house while the others are out roaming or hanging in one of their favorite spots i did finely see her squat for my male but she got up just as he was fixing to make contact.
Honestly i think my hen may be much older than i was told and may not lay at all but i don't care she is still beautiful and even old hens deserve a good home
