Two of my hens need aprons because of the rooster. One doesn't seem able to keep the apron on (I'll try another later), but I looked under the apron of the one who has it on and it looks like the feathers are growing back. Should I be increasing protein in this case or removing the apron so the new feathers get aired? These are probably stupid questions. I really need a few more hens and will do so in the spring.
