Last Friday pm we noticed "Red" was falling asleep standing up, lethargic, and ruffled feathers. Her poops are normal she was vaccinated as a chick for coccidiosis and Marek's as a newborn. We then noticed on Saturday she had a limp. We started her on save-a-chic Sunday and seemed to be in better spirits even hobbling quickly with the other chicks (still not up to par). Last night I used a little bit of regular water with the vitamin water and by evening the left leg was totally useless and she refused to put weight on it. I gave her only vitamin water over night and she is putting pressure on it this am but is still hobbling. Do you think this is a vitamin defiency or something else? My son was diagnosed with MRSA last week and does handle the chicks. So I wonder if he gave her something. She seems to be breathing faster than normal. The first pic is her in part of the brooder left leg facing camera and the second picture is of her outside brooder. None of the other chicks have a limp. Thanks for any help.
