Our clumsy pekin has started limping a bit and was slow to come up from the pond this evening then just laid down in the pen. Grabbed him to check his feet and legs and noticed he has a split nail. No blood but the nail is completely separated from around the quick in 3 pieces vertically separated. The end of the nail is broken off. I saw there are a bunch of posts on this for chickens but with it split like it is there is no clipping the pieces off without leaving an exposed quick about 1/2" long! Any advice?! He is already on an antibiotic for an infection in the other leg so hopefully it won't get infected.
