So I have 4 RIR and a duck (white, not sure what kind) I recently built a larger coop. The coop is about 4x8 foot and 4 foot high with 3 nesting boxes and a run that is about 8X8 ft and 4 foot high. After I built the coop I bought two barred rocks to add to the flock. Our RIR and duck where raised from the time they were hatched and get along. The duck thinks he is a rooster and actually stopped a fox attack by throwing his body at the fox when it got a hold of a RIR. That being said my new BRs are not as friendly, they are scared of people. I can work with that. Anyway we quarantined them for a month, slowly introduced them and let the fights go on. There was no blood and now all the chickens go in the same coop. However, 9 days later the BRs still get picked on. They are forced on a perch or nesting box and not allowed in the run at all. The duck is an absolute *** to them. I dont think she can hurt them but she pushes her weight against them and nipples on them non stop. Further more, we let our birds free range all day and the RIRs and duck do not mingle at all with the BRs. The BRs stay in their duo and my orginal birds stay in their flock. My questions are... How long does it take for the two groups of birds to free range togeather and form one flock? Does the duck change anything, will she eventually accept the new birds? What can I do to help this situation? My main concerns are we are going out of town and I dont want to leave them togeather in the run. The BRs will not get to the food in the run or in the coop. Any experiance in this would be great. Its almost been two weeks and from what I have read the pecking order is normally established by this time and the result is one big happy flock. I dont expect the BRs to come when called like my RIRs but I did expect them to range togeather and get along by this point. Thank you.
