I've done some home operating for bumblefoot. That's stressful enough, and there's hardly any bleeding. I can only imagine the amount of blood that would occur when dubbing such a large comb, which would be full of blood vessels. The healed pics look great. You clearly made a precise incision, which can be hard.

The dog got the hen, but she is unharmed... this time at least. Our hens also keep flying over our garden fence which is 3ft tall. Hopefully the clipping helps keep them out of the garden as well.
