It reads like it's food related behaviour.Hi everyone! I know this has been asked before but I have tried all the suggestions and I am at a loss as to how to proceed. I have a year old splash blue maran rooster who is constantly attacking me. I’ve picked him up and carried him around for hours. I’ve pinned him to the ground until he stops fighting. I’ve given him treats. He still attacks me as soon as my back is turned. Especially when I’m carrying food or get in storage where he knows their food is. I’m not going to cull him but I don’t know if there’s something I’m missing. I’m open to any suggestions. Will he calm down with age? So far he’s gotten worse
A change in how you feed him and his hens may give results.
