I had 4 chickens and the Texas summer killed two of them. My other two started molting soon after. They are finished molting and it's been almost three months with no eggs!!! Is this normal? Are they broken? They are two years old. We have seen a couple of mice around the coop. There is no access inside the coop so I dont think they're taking the eggs. They might be rats I didn't look too closely ----- could rats be somehow in the coop and TAKING the eggs? Or would they be eating them, shells and all, inside the coop? I dont know whats going on!
