Pigeon not putting weight on leg

[Pigeonator]

Hi everyone! I just saw that my pigeon was not putting any weight on his right leg he can hold the leg up however and when attempting to walk he will only use one leg and fall on is right side and just use his wings to get back up again. I put him seperate because they tend to fight alot. Any advice?

Is the bird improving? Can it grasp with its foot?
