She has killed 2 expensive cockerels and 1 pullet.Yeah she managed to get in one of my females pins today and killed one of them for no reason. I dont know what her problem is. But i dont think i could cull her ill push that one onto my dad LOL
No matter how sweet she is with humans, she needs to be culled.
If Dad can't/won't cull her, then then this is your time to learn. Everyone that has chickens will eventually have to put one down for some reason, so knowing how to do it quickly and efficiently is just part of being a chicken keeper.
