The hens are 2 yr. And over the last few weeks the eggs have decreased down to none. My hubby is the one feeding them but i just went in last week and noticed dropping on the floor that are not from chickens. We got a trap and cought a rat. I dewormed them also. Some have tons of feathers, missing so not sure if molting or other hens picking on them. Out in the run you can see where an animal has dug under the fence to get in. I covered the holes up but last night it was back. So what do I do. I plan on closing up the coop from the run but not sure if it will bite through the door.
