Sorry to hear about your rooster struggles! I recently ran into a similar issue with my rescue guy, but no serious damage was done and he has since been a pretty good boy. He started getting funny about food, and quick, jerky movements were startling him. The trick was to eliminate whatever he was interpreting as a threat. Also I try not to hand feed him anymore because he was getting too snatchy. I was also told that springtime hormones are peaking, so sometimes the flare-ups only last a few weeks and then everything settles back down. Hope you can at least avoid getting hurt, that is not ok!
@BDutch yes I acquired my rooster from his previous owners because he kept wandering into my yard for food! He is a bantam and was with a bunch of larger breeds that were probably getting better pickings. I sure am glad I bought him because since winter set in, he is the sole surviving member of his flock. Wish I could have saved more...Not sure what goes on with their animals but I think the chickens were left out in the cold. It's sad but I'm grateful at least for my boy! I found a small hen for him on craigslist to keep him company through the winter. Hopefully a few more hens once it warms up!
