Some 4 weeks before butchering day I start to feed them more animal protein to help with muscle build up (breast).Thank you for your response. They don't seem to even be aware of the girls at this point and there is no fighting. We have nowhere else to put them, so I guess we'll start processing when it gets to be a problem.
They are getting 18% all-flock like everybody else, along with a little scratch twice a day and a few mealworms. As in, about half a cup of scratch shared among the seven of them. Do you recommend something different/ better?
