Settling in new chickens

im afraid thats wot happens when you introduce new hens to a flock even if its just two.   A pecking order needs to be established.   Its all too easy to separate them when you see bullying going on but you are really best just letting them get on with it, the longer you keep separating them off the longer it will take for them all to settle down,  In the case of really bad pecking you can separate by taking that particular hen away for a couple of days out of sight, this will take her out of the pecking order and then when you reintroduce she should be at the bottom of the flock.   Hens can be really really nasty and its not pleasant to watch at all but since you have put them together i would just leave them to it, it usually takes a couple of weeks for peace to return, your doing them no favours by separating them all the time as you do want them to be one big happy family.     Oh and just another thing, it would probably be wise just to add another wee feeder and drinker away from your other one so the new girls can get access to food and water.    Good luck.  nickyx
