I've not been in this situation yet. Hopefully I will never have to do this, but if I do ever need to cull a chick I'll probably take the starter fluid route. I don't think I could snap or cut a neck.
I've got three 1 1/2 week old Polish chicks. I want to get some banties tomorrow, but I'm afraid the Polish chicks will hurt my newbies. Should I wait or use another brooder?
