I though it was pecking order..they are warren browns, a rhode island red hybrid (not sure what crossed with) I tried to get one of same age but the only had ones that were 5 weeks younger. they are being better now but still a little mean. Especially "spud" (number one in pecking order and not me lol) I have had chickens before. i didnt have to look after them then. Just the good bits. Totally unexperienced..I know how to love them tho and learning every day.
I hope you had an ok day despite the bad weather. Come to a sunny meet..much more fun
I still cant belive joel (hope thats right) is your twin.
