Bantam Breeds with very low aggression - looking for suggestions

[NagemTX]

i've had OEGB's but only hatchery stock. they were very sweet and charming and i adored them all except for the fact that roosters were HIGHLY aggressive with each other, which i recognize is likely an issue with the strain and that better-bred birds may be much better. at the moment I only have a single half OEGB hen but shes one of the sweetest and most charming little chickens I've ever had, and her brother was also sweet before he was eaten by a raccoon.. so I hope to use her in my project, but will consider revisiting OEGBs if I could find some with very little fighting instinct. Im also just interested in trying out some breeds I haven't had before, though I'm wary of pursuing anything too rare since I'm planning on crossing them all to different breeds and it seems like a waste lol.

My OEGB aren't that aggressive to each other but that could be because they are kept with alot of large breed roosters.
