If you change your mind about killing I found it easy to do with a hatchet. I was a baby though and put a sock over my sick hens head.She never struggled. I got a roo and he has NEVER attacked.Poor thing I chase HIM around.Got mine free off craigs when I posted looking for one.Lots of people offered their roos. So glad I got my Jackie Chan.He is the best. A good roo is so nice to have.
I would rehome or dispatch yours and try another. It is tough at first because you feel like you should have tried more,but like others have said there are soooooo many good roos out there.The peace you have from a nice flock is well worth a bit of emotional discomfort.Like with any animal you try your best,but you don't have to suffer with ill behavior just because they are your pet.
