This is my first rooster. I'm just trying to get an idea of what is normal, and what might be a big problem later on. We have a 6 month old SLW rooster. We got him with 5 girls as chicks to add to our flock of 3. Recently our older 3 hens started egg eating, so they are separated. They have their own small coop, very small run, and the 6 others are in a very large run and coop. They have only been separated for a few weeks. Because the 3 older girls are in a small space they free range for a good part of the day. My Collie does a good job on watching over them and we trust her. We like to let the "chicks" free range with them but the roosters behavior has me a little worried and I'm looking for ideas and feedback. The rooster is very protective of the 5 girls. He mates with the older 3 when they free range but is not protective over them like he is for his 5 girls he shares his coop with. One of the 3 older girls (RIR) pecked one of his girls (glw) and he went crazy. He ran over and was just chasing her around the yard. She doesn't let him mate with her very easily so it's hard to tell if that's what he was trying to do at first but really he was just chasing and attacking her. He eventually stopped when she ran on the porch, he wouldn't let her off the porch to join the others after that. Her comb was also bleeding a little in 2 spots. Is this normal? Was he just putting her in her place or should they not be in the yard together? He doesn't have Spurs yet, so I'm not too worried, but I'm not sure if things will be more dangerous then. He also has charged at my dog but hasn't actually attacked her. He did kind of kick his legs up at her but from a few feet away. My dog just tries to stay away from him but not sure if I should stop letting them free range. I don't want my dog to get hurt. Does this seem like a problem aggressive rooster or just a good rooster doing his job. Looking for thoughts and advice. Sorry it's so long.
