Something is going around my flock and I could use some advice. I have two chickens who have been laying shell-less or wrinkled eggs and just generally seeming below par. They have access to oyster shell at all times, so I'm not confident it's a calcium issue. I brought one inside yesterday after she stayed in the nesting box all day. I was worried enough as is, but today I noticed the other one has suddenly developed a limp. She is keeping her weight almost totally off her right foot and is stumbling and falling over. She's also a bit lethargic.
It could be a physical injury, but I didn't notice anything obviously wrong with the leg or foot (photos attached). Since she has been laying "eggs" overnight under her perch that are just shriveled up shell and yolk, I'm worried it could be something like Marek's.
I have found evidence of worms in the run and am treating the flock for them... But could worms cause this? Do you think something else could be wrong? Does anyone have any suggestions for treatment or supportive care?
