The best person to ask would be Chey_Aut as she has extensive experience breeding minis, but I agree that it doesn't look right. It isn't terribly uncommon to see that on newborns but I believe it normally straightens itself up within the first few days at most. I would have the vet and farrier look at it. Cute little guy may need some corrective trimming/shoeing or braces or something.
The sooner you get it looked at, the sooner some treatment can be started and the better the change that little guy/girl will begin to grow correctly.
The mini in the picture isn't mine. He is from the farm where I am getting my donkey colt. They have 3 mini babies this year that all have feet like this. This is the first time they have breed their own stallion so I was wondering if this might be something genetic passed down? I plan on asking them the next time I go out but kinda wanted to know what I was talking about before I started asking questions
I seriously hope this poor pony got help. This IS something to worry about! When a horse/pony is this young we can fix them, but as they grow older the epiphyseal growth plates closes. The 2nd Phalanx closes around 3month, and the 1st Phalanx closes at 6month. The growth pattern of the leg can (and will) be affected by the distribution of weight on the cartilage. This one is in need of a very good trim and some plantar and palmar extensions. For more information on this, google: tendon laxity (and please excuse my poor English).
