Hello, We have had our chickens for 2 years, they have been fine, but recently one has started laying eggs with no shells, and i have noticed her limping a bit. i have checked her and she seems fine otherwise, there is nothing i can see stuck on her foot. She was limping a while ago a bit, then it stopped and i have now seen her doing it again this week. Also last week she layed a wierd thing, that was meaty... There was a scare with a fox a little while ago, he got one of our girls but i'm sure the remaining too were in shock. We have 2 chickens in a roomy hours and pen, most days they are allowed out to roam the garden. The other chicken is fine. We feed them layers pellets, corn and they have grit/oyster shell available. They also get greens/ apples etc. Does anyone know what it might be? Many thanks for reading, i would really appreciate any suggestions.
