Hi: I need some advice about a possible bullying problem which has already resulted in the loss of two hens. I started out with two groups of pullets. One group from one farm had five sex-linked comets, two Rhode Island Reds, two white Brahmas, one brown Brahma. From another farm I got one white Leghorn, two Buff Orpingtons, and two Silver-laced Wyandottes. I also have a small rooster which I think is a Mille Fleur. The pullets are all about the same age, 4-5 months. My chicken house is a good size, 8x6. It has three roosts across the width all at the same height with plenty of room for all to roost. I have ten nest boxes with outside access on the left side (six blocked off). None of the pullets is laying yet. There is a full size door on the front and a sliding chicken door in the rear. The coop is well contained in a 16x16 pen. The chickens do not go out of the pen. The White Leghorn definitely seems to be the alpha hen and often chases the others around the pen. I noticed that some of the chickens, particularly the three Brahmas, one of the Comets and one of the Buff Orpingtons were sleeping either on the floor, on the hay box or in one of the open nest boxe, as if they were afraid to go up on the roosts, for fear of attack. About two weeks ago, I heard a large ruckus in the house in the AM. I discovered one of the comets dead on the floor, presumably from being pecked. All the other hens were surrounding her and sounded agitated. I could not tell with any certainty what happened. Two nights ago, the three brahmas stayed outside in an old cat litter box with a hood. Yesterday the Brown Brahma was reluctant to go in the house. I picked her up and tucked her into one of the nest boxes from the outside. (I wish I hadn’t!!). This morning when I went to let the hens out I found her dead in the same nest box. Again, I can not be sure who instigated the attack. Please can somebody please give me some advice? I would like to get some more brown brahmas to replace the ones I lost but am afraid they may be too timid to defend themselves. Should I try to isolate the leghorn if I can even catch her??I do not want to lose anymore hens. Please help!!! I have never had a problem like this before.
