Last Friday my peachick hatched and seemed fine, he wasn't standing yet, just resting in the brooder. On Saturday I noticed it's hock joint was red and swollen and it wouldn't stand at all and wouldn't straighten the leg with the sore hock. I cleaned and put tea tree oil on the sore area and wrapped it with the pad portion of a bandaid to protect it from being rubbed when he flopped around the brooder since he couldn't stand. Could he have been born with an infected joint or would it be from scraping it on the wire bottom of the incubator? Another chick hatched on Saturday and that one is perfectly fine. Both eggs were clean on the outside. Both chicks are eating and drinking and the sore joint has a scab on it now, but he still won't straighten the leg at all. He can stand on one foot now, but holds the sore leg up against his body. Last year I had a red golden pheasant chick that had a sore leg like this and it wouldn't eat or do anything and it died. That's why I wondered if they can already have an infected joint when they hatch. Has anyone else had this happen? I've hatched lots of chickens and never had this problem.
