I’m just curious if there are any breeds that you would stay away from and why
Anyone with feathered feet as I'd have to clean the feet. Apart from that, there isn't anything definitive, except for New Hampshire maybe. I had bad luck with my first one and haven't bothered to get any more since.
I also see a lot of comments where one person writes "x breed was mean" and another writes "x breed was nicest breed I've had". I've had both in the same chickens - where initially mean feather-plucking Barred Rocks ended up becoming nice later on. There's two reasons why this happened
- Slowly improving living conditions - new coop with TONS of ventilation, better and better run area, etc.
- Less Barred Rocks to non-Barred Rocks
The latter is almost as important as the former, I think. Each time a BR died, my flock got noticeably more peaceful.
You see, in my experience most BRs are bossy. They like to go out of their way to manage subordinate hens. Sometimes, this involves pecking, which sometimes involves feather plucking (most of the time this is accidental). So if you have a flock of half-bossy and half-non bossy birds as I had, what you have is half of your birds trying to go out of their way to boss their subordinates (including each other) around, which increases feather plucking. It also increases stress, as each hen can't boss and manage as they see fit without a competitor coming and bossing them around. So the less bossy birds you have (proportional to non-bossy ones), the less stressed each bossy bird is, and, the less feather plucking you get. I've also found that with less competition, bossing others around isn't as important to the BRs, and they take time enjoy life a bit more.
So nowadays I balance the flock with a small amount of bossy to non-bossy birds. I'd say around 1-3 bossy to non-bossy is a good rule of thumb (Once the bossies were only 25% of the flock, bald patches of feathers were gone). Rn my ratio is 1-13 bossy to non-bossy, lol. I planned for 1-3, but my other BR and my PR aren't bossy, it turns out.
Also, I know there are aggressive hens who do actually try to hurt other hens. I've never had an aggressive hen, but they are out there. I'm not here to discount other people's experiences, only to report my own findings. Since we all are dealing with living creatures with their own personalities, ymmv.
