Ours tend to charge us, try to get into staring contests with us etc. At this point, hubby wouldn't mind killing them but we feel the flock protection is important.
That's good to know. I mostly want to be able to touch them if need be (like if they are hurt) and I need them to let me pick up a hen or walk across the yard!
In our flock a rooster is expected to be respectful and tolerant of handling, even if he isn't thrilled by it. Any which try to challenge us or show any questionable intent go straight to freezer camp. There are a lot of friendly birds out there to be found and I have no desire to breed on aggressive ones. Hens are the same...you can get some who are rather nasty and they don't get to continue their ways.
Just be careful to give a rooster a fair evaluation...him getting irrate when there is a lot of stimulation going on (such as multiple kids and or dogs running around) may be more about his instinctual concern over protecting his hens from what he thinks is an onslaught of threats rather than him being an aggressive bird. However a bird who will stalk, charge or attack you from behind or without any provoking factors is a problem in my book. I don't have the concern of small kids running around but I use that possibility as a guideline for how well I trust my roosters.
And no, I see no problems with friendly roosters being less protective of their girls.
