We have a few Bantam Cochins. we picked them up a few weeks ago from a lady who we have gotten other chickens from. They were all kept in a big coop and enclosed run. The run was dirt. I do not believe they were ever let out to freerange. Some of them have signs of leg mites, which we are treating with Vet-Rx. The other problem is their nails. Some of the toe nails were caked in dirt ( and poop I'm sure) and the nails have grown very long and mis-shapen. A couple have nails that have starting growing sideways or almost in a circle. We have cleaned of the dirt. Should I now start trimming the nails back, or let them go? I trim dog and cat nails no problem, and I can only assume these are similar. I think that it would take a few different trims to get them back to normal, such that chicken feet are. Any suggestions or comments?
