I just got my first girls yesterday after researching for months and building my own house & coop. Got 3 bantams- black australorp, silver-laced wyandotte, and welsummer. All breeds that are, generally, supposedly pretty docile, OK with free-range or confinement, etc. I did a lot of research, I thought, since June... They were on a property with prob 200+ chickens being raised in pens for show, all in separate areas for each breed. Lots of chickens, small spaces. The australorp is freakin' killer ninja from hell. She's targeting the shy wyandotte 99% of the time. I don't know what to do. She's out for blood! That bird is PURE EVIL! She leaps into the air for no apparent reason and lands on the poor wyandotte's head, trying to peck at her head! She's only attacked the very-neutral and ever-so-slightly larger Welsummer once that I've seen. The wyandotte is receiving all the hate, and she's so scared! I don't know what I can do. I don't have an extra pen/coop to put Evil Ninja in and I'm worried that she'll kill the shy wyandotte. There are already loose feathers in the coop. Why would a chicken specifically target another chicken this way? I spoke to another chicken owner that said that her australorp was ruling the roost at HER house too, picking on others (all hers are standard, not bantam)... Are these birds just more aggressive than people claim? What can I do? Luckily, the wyandotte figured it out and now stays at least a foot from the australorp at all times. Whenever the australorp gets too close, the wyandotte dives behind the neutral welsummer to prevent being attacked. It's working thus far but it's VERY stressful to the wyandotte. She doesn't seem to be thriving from the extra space, good eats, and care that they're all getting now, at least not in the way that the other two are thriving. Should I just give it a few days to work itself out, as I've been advised? I'm worried, even though I know it's only been a day. Any advice is greatly appreciated.
