Hi - I've never posted anything here before. We have 2 Americauans and an Astrolorp. They've lived together happily for a year. All of a sudden tonight we heard chicken squacking in the middle of the night and heard thrashing around and thought there must be a raccoon in there attacking them but as far as we can tell, one of the Americaunas ("Feather") was fighting the Astrolorp ("Midnight"). The other Americuana ("Crystal") was quietly roosting through the whole thing. Midnight had blood on her beak but it didn't look like she was injured so it may have been Feather's blood. While we were checking Midnight out, we lost sight of Feather and couldn't find her. I hope we can find her in the morning but are worried about her. I guess my question though is what could cause two chickens to start fighting all of a sudden in the middle of the night after living together for so long in peace??
