I have 2 older hens and 10 pullets. 4 of them are about 26 weeks, the others are somewhere around 18-20 weeks. I also have 4 roosters that I can't wait to get rid of. Not one of them is laying. I had 3 hens that were laying and one died, I don't know why but since she died there hasn't been any eggs. It was really hot and humid here and I chalked it up to that but it's cooled off in the last few weeks and nothing. Food is the same. Most days they get out in the grass but they stay close because it's only for a few hours and I haven't seen any eggs anywhere. When they were laying before, they always went back to the coop to lay. I also have 2 silkies that were laying. One went broody, the other stopped laying too and now neither one of them is laying eggs. I'm pretty sure nothing is getting in the coop. The kids check it throughout the day so eggs would be pretty hard to miss if there were any. Any ideas? They are costing a fortune to feed and at the moment I'm getting nothing in return which is getting pretty frustrating.
