I have a 1 yr. old BA & Banty Leghorn. I have been trying to introduce two BR chicks, now 9 wks.-old. I started about 10 days ago by putting them in a wire dog kennel inside the chicken yard. The Banty, who I thought would be a problem, is doing the predictable chest bump/peck on head thing, the chicks scatter and that' the end of it. However, the typically docile, shy and cautious BA is being awful! She is just not getting used to them. Yesterday, I let them out of the dog kennel again to try to get them used to being together, I have to have this sorted out before I go back to work Aug. 29. Well, as usual the BA is horrible to them, grabbing them by the top of their necks---there are chick feathers scattered about! She "stalks" them and creeps in and attacks! Yesterday, I sat outside the pen w/ the hose and squirted her when she did it, or was about to, and that helped. I think she has figured it out though, and waits until I can't be there to attack. When do I just give up? I don't want her to seriously injure them, and hiding under the coop is no life for the chicks. What should I do? I am so upset.
