I have 20 birds in the flock right now, 19 ladies and my Romeo. I have noticed a marked difference in the backs of the ladies which seems to depend on the breed?? Is that possble that some breeds' feathers break ore easily under the roo's feet? I keep his spurs really short so it must be nail damage. Barred rocks show no sign of his having been there at all. Buff Orpington no real damage. (I only have one of them and the roo seems to leave her mostly alone. ) Delawares little damage, some thinning Rhode Island Red no damage The Rhode Island Red Delaware sex links (not my own cross breeds) --- massive damage. Many of them end up with bare backs and as soon as their backs start to show next thing you know the back is red and naked. I tried saddles, but the feathers under the saddles broke off and did not seem able to grow back.... I currently have 3 separated from the flock to let those feathers grow back but gosh they grow slowly!! How long should re-feathering take? Has anyone else had this issue with this breed? I know it is a fairly common breed in the DelMarVa area.
