Where to start??? 12 hens, 1 rooster. First, the hens seem to be pecking the roosters feet until they bleed. We took him out of the pen/house and put him in a crate, dipped his legs in vegtable oil for a week, seemed to look normal put him back in the hen/coop and they pecked them up again. (Emptied and cleaned the coop, put down sevin, re bedded it and the nest Have never seen a mite, been lookin. 12 hens went from 9-11 eggs a day to 4 One hen brooding, won't get out of the nest much loosing weight. About 4 hens have a bare spot on their back where all the feathers are missing. These chickens were born January 21, 2010. We live in Mississippi and it is not that cold out, actually getting warmer! What is happening to my happy chickens!
