I agree with you. I don't feed my hens meat or meat by product. They are free roaming so they do get an occasional frog, that seems to be a big treat to them
, but that is the only meat they have had. I'm not saying there is anything wrong with it, just don't see it happening with my brood. I did have trouble when my hens started laying eggs, I had one that wouldn't go in the nesting box and she laid soft shell egg, so the others hens would pounce on the egg like vultures
. I would try to time it so I was out there to immediately get the egg.(Didn't want them to get use to eating them and leave me none) Some oyster shells in their feed and coaxing into the nest box solved that problem and I haven't had to share an egg with them since.
