I went to go pick up a self blue cochin was told she was 4 months got there Cleary not 4 months !! She was very dirty and smelled awful !! Brought her home to her new set up for quarantine later I noticed her crop looked like a water balloon took her to the vet he said she appeared to have gorged herself on food ! And she was infested with louse and was malnourished!! Removed her food left her water wasn't completely gone next day gave olive oil and probiotic in water ! Today It had gone down but with a little food it's squishy and balloon like again but not is large !! Does this sound normal or is it something wrong with her ?
