Need help finding information about a foot disease my chickens have

[nmalcom14]

I ordered all my chickens from an online hatchery 2 years ago and all of the dominiques I ordered had deformed feet (it looks like their toes were broken). They have been doing fine until recently. Two of the dominiques have died within the past two weeks and I can't figure out what is wrong. The chickens bodies were unharmed and just dead on the floor of my coop. Some of my other dominiques have been acting sick lately also. So I was wondering if any body here knew anything about this disease they were born with and if it could be harmful to the rest of my flock?



- Thanks
