I've got 9 chickens. 6 of them are only 5 months and the other 3 are 2 year old silkies. My silkies have laid very reliably since I got them about 4 months ago. All of a sudden I've got no eggs in almost three weeks. No major changes at all. After a week and a half I went through and cleaned thoroughly, added some probiotics to the water for good measure, they get good scraps added, per others ive tried some cat food for protein, some and some scratch... Still no eggs. We put a game camera out and didn't see anything outside stressing them. Isn't it weird that all three of them have stopped? I haven't seen any evidence of them hiding them or breaking them.. Help!
