I have 25 Red Bourbon poults divided into 5 groups (They are each in a separate pen with their mother). They range from 8 to 12 weeks old. However, they are outgrowing their pens and so I've made 2 new large temporary pens and one more pen is in the works. (I am planning to sell them for Thanksgiving.) The problem is that everytime I try to introduce one group to another, they just attack each other. Last time I had 9 lovely poults and put 2 more in with them, the 2 new ones went after the 9 slightly smaller ones, pecking each of them hard in the back of the head. It looked like it would escalate and possibly result in injury or death, so I took the 2 back out again. I also tried to free-range them together thinking all that open space would reduce the fighting, but they still pecked and fought hard with the smaller ones. I recently found one of my 12-week-old females dead and I believe her two siblings (toms) killed her. There is no way I'm going to be able to build enough pens to keep them all separated. Also, I think that the Red Bourbons (and any heritage breed) is different in this instance than the Broad Breasted Whites. I've seen the BBW raised in huge groups with no problems -- they just seem to get lazy whereas mine are very active and protective. Those of you who raise turkeys, please, tell me how you do it!!
