I'm sorry no one has replied. Try reposting in https://www.backyardchickens.com/forums/emergencies-diseases-injuries-and-cures.10/. Can the chick move the leg/walk?
It rather looks like an abscess. I would try soaking the little leg in an epsom salt bath, and when the skin is warm and supple from that, you may be able to release whatever is in there. There is a whole process to treating abscesses. I personally have treated them by lancing, flushing and dressing, and of course, keeping everything extremely clean. @redinator What do you think?
I was thinking along those lines, but haven't had to treat a chicks leg myself, so I wasn't sure.
It looks from the yellowish circle-thingie, that this area has burst open before, sealed back up, and the swelling may be pus or fluid build up, that if released may ease discomfort and mobility challenges for the chick...
Chick can move around on one leg and wings for balance. Eating and drinking fine. No pasty butt or other issues.
I will try the Epsom salt soaked bandage. How long should I leave that on for. I had thought Epsom salts too but worried about her not drying out quickly and getting too cold. I also have colloidal silver and silver honey. I have amoxicillin that I can dissolve in water. Would any of that help? This is the first time I’ve had to deal with this.
So sorry to hear! I'm not sure what to further advise you. Perhaps the silver honey will work, or if you have raw honey, like Manuka. I've personally not use colloidal products, but great success treating infections and wounds with Manuka honey, even tumors. As @redinator advised, I would post to https://www.backyardchickens.com/forums/emergencies-diseases-injuries-and-cures.10/. I would also search on this site. It's such a vast resource, surely someone else has dealt with similar if not exactly the same. Wishing you all the best with you sweet little one.
The bandage will probably get dirty pretty quickly so I'd change it as often as needed and see if the abscess has softened to be able to drain/flush it. Get a saline solution to flush it with . . . it should sting less than the Epsom salt . . . as of now you can't really treat the problem until the scab/crust becomes soft and it can be drained/flushed. Oral antibiotics might help but I don't know which to use or dosages.
