Yeah, been there. If I don’t thrust them I keep the hens confined to the coop and run a whole day. And when I open the gate I follow the fastest one go to any hiding place.If you free range at all, they may have a secret stash of eggs somewhere. I just found a nest with almost 20 eggs yesterday.
Whenever I found eggs in a secret nest I kept them in ‘prison’ for a few days. This really helps a lot. Haven’t done this in a long time now.
