My chicken has been having a hard time walking, initially she was hopping on one foot and now she is struggling on two feet. She is panting. She is eating fine, drinking, and laid this egg today. Does anyone know what is on it? I am wondering if she has a broken egg or something in her? Please let me know if you have had a similar experience. Any suggestions. I brought her to the vet on Thursday. Vet said she might be egg bound. She laid an egg on Tues. Wednesday and thursday, none on Friday and this one today. She is just about 6months old.
