Hi Bonz, thank you for replying. I mentioned in my original post that the chickens had all been in adjoining pens where they could see/smell/hear each other for over a year until we got the awesome new coop and run built where they could all live together. (HA! that didn't work out! lol) So the getting used to one another by sight didn't work in my case. To be honest, I see that suggestion for integration constantly and cannot figure out why it didn't work for my girls since it is such a popular practice.
Free ranging is absolutely forbidden in my town. We are allowed a max of 10 birds, no roosters and no free ranging. (As mentioned, I have only 5 chickens, I do have 2 ducks also but that is not relevant here) Even if free ranging were permitted we live on a busy street and have many stray dogs that roam the neighborhood.
All of my girls are the same age and basically grew up together, short of the adjoining pen deal, as chicks and pullets they all shared the same brooder and then pullet pen and had no issues. As a group they outgrew sharing the one pen so we had to separate them into the adjoining pens I've already mentioned. By adjoining pens I mean that the 3 pens all share wire "walls". I suppose I could have somehow removed the wire walls so they were all together but didn't think about it and everything was working out just fine as it was. Since they could all see each other and talk to each other etc in the adjoining pens I figured pecking order would be a relative non issue but boy was I wrong!
As I also mentioned in my original post, I give them treats to distract them such as whole pumpkins, heads of cabbage etc. but that never stopped the reds, if ANYONE came near THEIR cabbages or pumpkins they were immediately ganged up on and made to bleed. I tried to set out 2 of whatever I was giving them (2 pumpkins or 2 heads of cabbage) so that the reds could have one and the rocks could have one but the reds would "divide and conquer" one red to each pumpkin but in their eyes, everything is theirs and no one else gets any. They would race from pumpkin to pumpkin around the run to attack the rocks and it wasn't just a peck or chase, they would pin the offending rock down and beat the snot out of her. I would have to literally get a hold of the red and pull her off the rock, there was constant blood shed for days and days. So, as I said in a previous post, the reds are now in "chickie jail" as we have come to call it. They cannot see or hear the rocks and the rocks cannot see or hear the reds. They won't be up for parole for another 9 days.
Thank you again for your tips and suggestions
