So, I raised these guineas with my chickens, always get along fine. Actually, when free ranging I sometimes will see my rooster wondering the yard with the guineas instead of with the rest of the hens. Anyhow. Today I let the chickens free after work, like I always do for a few hours. I heard some noise an hour or so later, and I look out and the rooster was fighting with a guinea. Really really fighting. I went out and I couldn't get them to separate, the rooster just kept wanting to go back for more (typical male? ). There was a little bit of blood, but I got all the chickens in the run and watched everyone for a while... things seem okay. but I did notice that the coop/run door had somehow gotten shut (maybe the wind?) Is it at all possible that the rooster got stressed because it was starting to get dark and him and his girls were stuck outside? or is that wishful thinking, and you think I am going to have a guinea vs. rooster problem forever?
