I researched chickens for 1 year..I wanted docile. 6 months ago I got what I was told we're long island reds. I have 6...free range..but cooped at night. They're red. But yellow fluffy tushy. Most are sweet. But 1 is Satan. Picks on the others. Really chases 1 and hurt her eye. She's the sweetest. Do I get rid of Satan..how do I find out true breed?
