We had to separate our 10 week old roo from the pullets. He was harrassing them. As soon as we separated him, he stopped crowing and went back to the very cute little meeps, peeps and chirps. He seemed really lonely. As we can not have roosters where we are, we found him a home on a large chicken farm. Hope he leads a long, happy, rooster life. It is bitter sweet. He was beautiful.
