Welcome to BYC. Is it at the hock or elbow? is the hock swollen? Can the chick stand and walk? Sometimes a hock can be swollen and red from a slipped tendon or bone deformity causing pressure on the tendon, but mycoplasma synoviae infection in the joint can sometimes be a cause. Can you try and post a picture or two?
Wow, thank you so much. Luckily today my bro-in-law came over and looked at it. What he saw on the inside of the leg that i thought was dried puss was (believe it or not) a small rubber band wrapped around its leg. He removed the rubber band which was of course embedded in the skin. We have soaked his leg is salt water and we're keeping neosporin on it. We have no clue how it got there unless the seller used it for marking chicks or something. Already the swelling has gone down and hopefully he'll recover completely. Thanks everybody for your imput
My goodness, that is wonderful. I hope that the circulation in his leg will become normal again. Thank you for posting this. It may help someone else. Please give an update on your chick soon.
So far so good. We've been keeping a close eye on him constantly. The swelling seems to have gone and the little guy is getting around much better already. We're still going to keep him by himself until he fully heals though
