The mean ones will puff out their hackle feathers and bit hard enough to draw blood. I have two Partridge Rocks doing this now. They have tickets to freezer camp for SaturdayThanks! I hope everyone is right that I have a some more time. I became concerned because one of the olive egger roos grabbed a Basque hen by the neck and she screamed and ran helter-skelter all over the place, afraid of everyone. There are 2 olive-eggers I've seen doing this.
I have not seen any fighting, just normal chest-bumping type challenges.
I'll have to try carrying them around. Just today, I did try picking up 2 of them just for a second.. One squawked, but was indifferent when I set him down. The other bit me a few times. The smaller one that is brownish does not let me get close enough to even touch him.
What is it with the biting, anyway? One of the hens immediately starts biting my shoes when I walk in, and will bite my legs the whole time I'm in there, or hand, if I reach towards her. All the Basque are doing this, but this one hen is the most aggressive. That is why I call them "curious" or "bold", not "friendly". They are an interesting breed, anyway.

I have limited experience with Roosters, so keep this in mind. If the Roos are raised together they probably will not kill each other. If you separate them for a couple of days and put them back together then they may try kill each other.
Only one Basque Roo(had 5) has bitten me, and not hard. None of the pullets bite(had 6). pecking at the shoes sounds like looking for food.
Some of my other hens will peck at my freckles.
