Well - after trying everything I had read on this forum and some things my grandma gave me advice about, we had to cull my crazy 6 month old roo. He had become so mean that everytime I came near him or any of the hens, he attacked. I hated to cull him, but with small children I felt like I had no choice. One good thing that happened yesterday however was I got 10 eggs, the most ever. I have 11 hens so my girls are doing a good job. I do plan on getting another young roo and with my new knowlegde, hopefully he will be a easier to deal with. Thanks to all who gave me all the info on problem roos. I will be using it again to train the new roo.
