Is there a “normal” amount of fighting?

TW the second photo is of some light blood spattering. The first one is just one of my pretty girls ♥️

Hi! I’m curious how I can tell when/if they’re fighting too much.

I have 8 currently. They get let into their yard when I’m not home and then I let them free roam when I and the dogs are nearby to keep an eye out for any lurking predators. I let them out to free range this afternoon and I noticed some blood spatter on their water feeder. This is all fresh today because I cleaned and refilled it last night. They’re all acting normal and I can see where one got her comb pecked.

Should I be concerned? How do I make sure all my ladies are getting along?
