I just had some eggs hatch in the incubator 5 days ago and one of the chicks is super aggressive with the others. It attacks them constantly, unprovoked. I lost two chicks and suspect it was because of this wee firecracker. The breed is RIR. This is definitely not the normal pecking order behavior. I have separated this chick starting yesterday and am handling it most of the time or it cries. It has stopped attacking me now but as soon as I put it back with the others the behavior resumes and the other chicks run and cower. I'm giving it a few days but does anyone have any suggestions or experience with this?
