Our EE roo isn't very nice, he's got a ticket to join us for dinner, he's just waiting on my hubby to punch it

I have been putting off processing any chickens, I've been needing to, but just haven't gone through with it yet. I have a flock of egg eaters that are slowing down in production and I can't add more chickens in with them to be taught to eat eggs, and I can't move them from the coop they are in to another coop as they require the rollaway nesting box. Can't rehome them to have them teach someone else's birds to eat eggs...
