Just an Update!
The pullets are doing great now. The ones he attacked have some pretty rough feathers on the back and heads; but with doctoring and generous amounts of Blu-Kote they are doing fine and not being attacked by the others.
They come out of the house more and ate from my hand this morning and walked on my feet and hung out close to me. Before they were pretty skittish of me and stayed in the coop more. They also make contented clucking noises a lot. They have been zooming around more(head down fast running ha-ha), I think maybe they were afraid the Roo would freak if they did that before. So I think they are quite happy without the rooster and I am too. Thanks for the advice!
