Sorry for the length.... I have had chickens for a couple years now. However, this fall it has been a challenge with my flock. We decided to add more to our flock as planned out from a year ago. But it has not gone as planned and I am looking for some advice. Our coop is 8x8 on 4 ft stilts and clear pvc paneling around base for winter. A 6’x12’ green house is joined to the pop door on the bottom of the coop to add extra space for the winter during frigid weather when they don’t want to free range. The greenhouse door is almost always open to the 1 acre yard except if it’s cold , windy or snowing ❄️. We got our 4 Wyandotte 5-6 month old pullets (born in May and June 2018) and had them in quarantine from October 27 to Dec 2 in a temporary rope fence and tiny coop. Then added them in the top of the main coop behind a fence with the look but no touch method for a week. While they were in quarantine I discovered my main flock developed a severe plucking and picking issue. At first thought it was molting but later discovered it was a behavior. At this point I could only go forward with the pullets after resolving the main flock issues as it’s snowing and frigid below zero weather is setting in. After a week of look but no touch method I let the pullets out in the yard to free range on a nice sunny day and watched. The Queen hen was aweful, chasing the pullets and pulling feather, looked like aggression. She did not like them in there. The other 3 including the rooster followed suit and the poor pullets cowardly sat in a ball as all of the flock ganged up on them. It got worse the closer to the coop the pullets got. So I took Queen out of the mix and let the pullets sleep in the greenhouse a couple nights. Then it got below zero so I added them to the main coop, looked like all was going ok. The pullets still hang out together and mostly avoid the main flock of 3 but no major bullying in the coop in the morning or at night (all are sleeping on separate sides in the main coop). Rooster pecks them occasionally and runs them off when in the greenhouse or underneath but not much that I can tell. Then today I added the Queen back in and it all stated again. At first she minds her own business then out of no where chases them down grabbing tuffs of feathers. Then the others join in. I know “the pecking order” has to be established but when is it bullying vs pecking order integration. Does any one have any ideas how I can integrate the Queen hen with the pullets? Right now I have Queen and the pullets in the greenhouse together. But separate and in sight of the others in hopes that the 5 of them work this out without the gang up approach. Will this work?
