Twisting bones???

[Mariella posey]

Okay, so we had a turkey poult that we noticed had a bit of a crooked leg and it kept getting worse. It got so bad that he couldn't walk and just pushed himself around on the ground, we ended up just putting him down. We cut the meat off that leg and the bone had twisted. There were no breaks of any kind and we were adding vitamins to their water but nothing was helping this little guy.
Now I noticed one of my roosters that had a straight leg when he hatched has a crooked leg and it's getting worse.
Any ideas as to what's going on?
We will be culling the rooster soon so I will try to get a picture of the bone.

Are they getting enough calcium? That's the only thing I can think of.

Without seeing it, hard to say. It could be from a slipped tendon which can result in a rotated femur. It also could be a bone deformity.

There are a number of leg problems, such as slipped tendon, but the various leg bone deformities are common in meat birds and laying chickens. The turkey sounded like it had tibial dysplasia (TD) where the bone actually twists as the bird grows. Varus or valgus deformity cause the legs to bow out or turn in, and those can occur in one leg or both. Then there is twisted tibiotarsus or twisted legs. Make sure that your birds get a balanced feed, since vitamin D3, calcium, and phosphorus must be in a correct ration for leg health. Here is some info:
