Our favorite rooster, who is fairly new, came to us with a swollen and sore leg. I thought it had been from transport, so gave him a quiet place to rest and keep an eye on it. After a week, it only seemed to be getting worse. I took him out today to get a look at it, and it was very swollen and had several areas that seemed very fluid filled. Ive dealt with similar issues assisting farm vets before so I decided to see if he would tolerate lancing it to get a better look. I BARELY touched it with a sterile scalpel blade, and it was like someone turning on a garden faucet. The rooster never budged, wasn't panting or distressed, and was only concerned at first when touching the swollen leg (before draining at all) since it was sore and after the thin bloodless pus like fluid drained out he didn't even care about that. So I started gently feeling for lumps, thinking maybe there was a splinter or other foreign object that somehow found its way into his leg. I found none. What I did find was a very hard yellow core surrounded by thinker puss. In fact, there were several of these I located and removed. (Our roo was fine the whole time) After this, his leg was almost normal size and after cleaning it up with disinfectant and gently wrapping he even puts weight on and uses it now. What I am curious about, is what these cores are or if anyone else has seen this before? I took a pic of the cores, which are a little dirty from falling on the ground but shown below, but not the leg or process. I was too focused on helping the poor guy once I saw how bad it was to pause and take pics. I think if I can keep the infection at bay, he will be fine now. He seems MUCH happier with his leg at this point and is eating/drinking normally. Also interested in any other information that may help this guy. He is my sons favorite rooster right now, and one of the absolute gentlest birds I have seen. He will snuggle into your lap and nestle his head into your arm. My son loves him. Hoping to integrate him into the therapy program soon, so he will likely be headed to the vet if the problem is not resolved by this procedure. Unfortunately, it will likely be a long and costly trip from where we are to where a vet that can work with him is. Thanks in advance. Edited to add that this bird is an older bird, id say at least 2 years old, and the cores were all located between the top of the back toe and where the feathers meet his leg skin. None were on the bottoms/pads of his feet at all. Also, these core have not been rinsed. This is how they looked. He bled very little, mostly there was puslike fluid, which did concern me until I saw that he uses the foot now so there is feeling still. Came out in tact. Tried to mush a few open here.
