Not sure if this is the correct forum to post about this. If not, MOD, please move this to the right forum. So, I had 5 four-months old birds in my backyard (one female bantam, one male rhode island red, one male plymouth rock, two hens). This past weekend, I introduced two female barred rocks to my back yard (one one-month old, and one two-months old). The new pullets have been pecked on by the other chicken who are two months older than they are. The two were being pecked no matter what they do. When they come near the food of the other 5 chicken, they would be pecked on to the point that they would hide in the corner, shaking badly all over. I am really angry at my older birds, even the bantam who is no bigger than the new comers in size. Should I separate them? Will they eventually peck the two new comers to death? Or, will they eventually be come friends? What's the strategy I should take? Thanks for inputs.
