I introduced 2 new ladies (7 months old RIRwhite and Araucana) to my 2 resident ladies (8 to 9 months old Sexlink and Java). The 4 of them are in a largish run 8' x 12' x 6' high with roosts and small covered areas etc but one of my resident ladies is just death on the 2 newbies (even though I kept them close for a few days (but apart) before actually putting them 'in' together. Will they ever become friends or at least tolerate each other? OR will the literal back biting and feather pulling never stop? My resident lady (Sexlink) has put Fear into the Hearts of the new two chickens and she is really vicious with them. Will it stop? Should I separate them? Re-introduce them? Or is this just a common example of "pecking order?" The 2 new chickens are hovering and hiding and darting about. Nobody is relaxed at all. My next question is - my 2 new ladies are not nearly as socialized as my first 2 ladies were when I got them. Will they calm down into pets? or once a wild chicken always a wild chicken? I should say I'm also fairly new to raising chickens.
