I feel this is a bit more than pecking order but I am new at this. I have 3 Bared Rock's, 6 RIR, 5 Black Austrilorp's and 3 Delaware's. For about 3 weeks I kept the 3 Delawares in their separate cage/pen sharing the same water as the bigger girls. Oh, there is around a 3 month difference in age. Late June to late September. So last week I decided that the introduction was long enough and put the 3 in with the rest of the flock. Right off the bat a BR went after them. I stayed in the coop with them to make sure it didn't get to out of control. I sort of would stop it if it seemed a bit to much. The 3 D's stayed together and went to the highest roost and stayed there. I left and came back later and they were still up high on the roost. I do have a couple different water and feed stations. Anyway I went out the yesterday day and the 3 were all together under this lean to board I put in there for them to hide if need be. I had them get out so the could eat and drink, and one of the BR went right after them. I have the introduction cage still so I put her in there. Went back in the coop and a RIR were after the 3 D's. Also, as soon as they came out they went right for the food station I have away from the one that has been there from the beginning. You could tell they were starving. I stayed there to make sure they ate what they wanted and drank. I think it would be better if they went out in there run, but we have a little snow and they don't seem that interested in going out. Do I need to let this work it's self out or what? Also not once has the BA's went after them while I have been out there. I do see them stand up to the others and even do the pecking order thing with the RIR's and BR's.
