Here's the background... this is my first experience with chickens and they were well started when I got them and just starting to get their feathers in. they came from the same brooding box, got along well and so forth. When they got big enough, I put them in the coop which is large enough to support 12+ hens (I have 6). Just recently, my one hens started attacking one of the other hens for whatever purpose. I dont see any damage so far to either chicken but I dont know why this is happening. They have plenty of feed, water and so forth... so why is this happening all of a sudden? They are americana x and it seems that its only 2 of the hens that are showing aggressive tendendices. They were supposed to be sexed so should be all hens. What can I do about this? should I be worried about it or is it just the hens figuring out the "pecking order". Any advice would be good here.... Thank you for any assistance you can provide. I can get video of them doing this if it would help.
