Back in March we purchased 8 ISA Brown pullets based on the temperament and egg laying propensity of the breed. We already had 6 white leghorn hens and a rooster so we were the plan was to add to the flock to get the male/female balance more in alignment. After 4 months the ISA Browns are all bigger than my existing hens except for one. Additionally 5 of the birds have combs, wattles and small spur buds. Some make attempts at crowing, and they are constantly mounting each other in a breeding way. As soon as I think I have identified one as being a rooster due to his behavior, that chicken will be mounted by another one. Everything I have read indicated that ISA Brown Roos are white with red spots. All these chickens are predominately red with white spots. I have added pics. Any help will be greatly appreciated. Not sure what I am going to do with 5 Roos now. I will say that they are very friendly and like to follow us everywhere when we are out in the yard - so they are worth having just for the entertainment value! Thank you BYC community!
