Hatch defect need help

[OblivionChooks]

Red, slightly swollen and Fussed knees in a chick? Is there any hope? He is a belly crawler, I noticed the splayed legs first and I put a little brace on him. I have since noticed his knees are red, slightly swollen and fussed. He cant straighten them. What can I do for him?

Where did the eggs come from?

Poor thing. Can the legs straighten at all?

You could try making a chick chair for him. The swelling and redness are concerning, I would worry about infection or disease like Mycoplasma Synovaie.
Gently clean the joints with something like Hibiclens (Clorhexidine) or Betadine. Apply triple antibiotic ointment or Vetericyn.

Is the navel closed? I see what looks like poop/egg sac on the rear as well.

Sadly, sometimes a chick with leg issues needs to be put out of it's misery. I'm sorry.
