I will have to look and see where ours is, we used to have one just like that.Last March a friend & I purchased 18 just-started-to-lay hens from a seller that had about 50 hens and was overwhelmed with eggs. We went in the coop & caught a few of these & a few of those. Put them all in 3 or 4 crates/boxes.
When we got home one of the hens had reopened an obvious old compound fractured toe. It had "healed" with the fracture & a good bit of bone exposed, no doubt from continuous re-injury of the toe. I had no choice but to amputate her toe. I did it at the fracture so I was only cutting through tissue, not bone.
I bandaged it up which stayed on for about a week. After she lost the bandage bone was still exposed and I feared I was going to need to cut the bone back so that hopefully tissue would heal over the end of the toe. But I dreaded doing it and kept waiting to see. Tissue eventually healed over the bone.
I used a pair of dog toenail trimmers (like these http://www.amazon.com/Safari-Professional-Large-Nail-Trimmer/dp/B0002ARQV4 ) to amputate her toe. I have photos of before & after the amputation, should update with a healed photo. I could post them if they wouldn't be inappropriate for the group.
