Hello, i recently added a new chicken (perry) to my flock of three, and she just started laying. her first egg was a bit mushy, but I figured it was a one time thing. this morning I found this.. thing around her cage. its also completely mushy, with no shell. I did find a slimy coat wrapping around the white part of it. Is this normal?? I really need her to start laying normal eggs, I have switched her to laying feed, and given her some oyster shell grit. is their anything else i can do?
