This chick was given to me by a friend and was malnourished so it is smaller than my other 8 week old chickens, BUT Oreo could also possibly be part Banty. It came from my friends free range chickens and her neighbor had chickens as well. he/she had not displayed any rooster like behavior until today. Today Oreo has sort of attacked some of the other chickens twice his/her size! By grabbing the feathers on their neck and not letting go until it gets shaken off. like I said the other chicks are TWICE the size of Oreo. WHAT DO YOU THINK??
The combs on all 4 chicks I got from her are irregular the points are all different sizes, my 4 week old bantam roo has more wattle than any of them. Also, how soon do roosters start to fight?
