Just don't try using any painkillers, all of the -cain drugs are really hard on chickens and could kill her from the drug alone. Chickens are good at handling and getting over pain quickly (as you can tell by her not being bothered by the big hole in her neck). Not to say you should inflict pain unnecessarily but using sharp scissors or a scalpel to quickly remove a skin flap shouldn't bother her too much.Thank you. I’m going to discuss these options over with my brother and see what he thinks the best option would be. He’s more experienced than me. I’ll keep posting updates in case anyone else is interested in the outcome.
