Lump on pullet leg

[Ruralgrl]

Do any of you know what this could be?
She is a 7 1/2 week old Maran. She started limping last week but is acting fine otherwise. She has this bump on her leg. No mites that I’m aware of. Her scales and legs look fine otherwise. She does hold her tail in the down position but always has so I assume that is just her breed. She’s my first maran though.

Can you get a video of her walking?
Does the joint feel hot, any inflammation on that lump, is it hard or soft?

Not sure what the lump if from.

Her joints feel equally warm on both sides. The lump is hard. I took a video. How do I post it? Haha after watching the video it does seem like her leg is not straight.

For video, upload to youtube and provide a link.

Can you take some good clear photos how stands showing her legs from the front and back?

The bump on her leg almost looks like her bone is sticking out, maybe her leg is dislocated?

Looks like it may be a bone deformity that is presenting itself as she's gotten older and heavier. Maybe Valgus form. If that's what it is, then likely you won't be able to correct it.
I would however give her some B-Complex to help with Riboflavin. Give 1/4 tablet a day for a week, then taper to once a week.

I'll tag in @Eggcessive and @coach723 they may be able to offer better suggestions or recognize something else.

I agree with Wyorp Rock that it looks like a valgus deformity of her left leg. If valgus occurs in both legs the legs would have knock-kneed appearance. The opposite of this is varus deformity, which causes a bow-legged appearance in one or both legs. Neither condition is treatable, but the chicken may get along well enough to live a fairly normal life. I would guess that the bump is a boney prominence. I’m not an expert about any of this, but you can read and see some pictures of the same defect and others in this article:
