My 2 4 week old BR's are velociraptors! I have one larger brooder with the two BR's on one side and my 2 week old BO's on the other separated by hardware cloth. They have been looking at each other through the screen for weeks now so I thought I would try to get them acquainted. OH BOY! The big BR's went after them like mad! It went on for about 30 min and the divider went back up. The BO's are so sweet, and quiet. They jump up on my hands and love to hang out with you. The BR's are loaded with personality, but will take your hands off for yogurt, or grapes. They hate being held, but are very lovable girls with each other. Will these guys ever get along? Does anyone else have these two breeds together with any problems? They are very different in size right now and I am assuming that is part of the problem. The BR's are just way more boisterous and aggressive. Am I worried for no reason? You can get an idea of the size difference in this pic.
