Knock knee?

[Soontobehens]

I have a three month old salmon faverolle rooster that seems unsteady on his feet knees kind of give out when he walks and I’m worried he has knock knees. Is he young enough if it’s a vitamin deficiency to fix with something like poultry cell or nutri drench? This only started a week ago maybe. Did he grow too fast? Wish I could attach a video of him walking

It may be a vitamin deficiency or something like Mareks. I would try daily vitamin drops to see if it helps.

Vaccinated for mareks so I’ve ruled that out trying poultry cell for a few days hoping it helps

Vaccines don't always prevent Mareks unfortunately.

It sounds like valgus leg deformity which causes a knock kneed appearance. It can occur in one or both leg, and the opposite problem is varus deformity which causes a bowlegged appearance. Here is some reading :

Here is a thread showing one leg with valgus deformity:
