Aggressive Guineas

[Elisi]

I had a mixed flock of 12 Guineas. They are free ranged during the day and return to their barn stall at night. There are at least 3 hens that have gone broody and so there is a lot of aggression right now. Tonight I found 2 dead birds, 1 out in the barnyard, the other in their stall. The one outside had a whole in its side about the size of one of their eggs. My question is will they fight to they the death?

It's normal for a flock of Guineas to decide to ostracize a particular bird from the flock, and pick on it to the point of killing it, but with 2 dead (and the 1 with the whole in it's side) it sounds more like it could have been a small sized predator attack to me. When Guineas attack/fight with each other they usually corner the targeted bird and then continually attack the head and neck area. Did the bird in the stall have any injuries, or possibly a broken neck? Sometimes they can panic and hit the roof breaking their neck or sustaining a severe head injury. Do you have hawks, weasels or owls in your area? Just wondering if a predator got into the stall with your birds, freaked everybody out but only ate part of the bird that was outside.
