I hatched 3 shamo chicks which are 3 days old now I read they were friendly and made good pets if handled everyday.I know they are fighting birds and wondered if their behaviour is normal,From 2 days old they seem to be very aggressive,they are in with some silkie chicks hatched the same time and are fine with them no aggression whatsoever but when I put my hand in the brooder they rush over to attack pecking like mad and really strutting,the other chicks are very gentle,I can only see this behaviour increasing as they get older is this normal for shamo?
