I have three silkies that I hatched from eggs- they are very likely siblings. One is female, and the other two are males. They are about 2 months old. They have grown up together. Do I NEED to add some more females? They are in a dog kennel with a coop inside of that. I am about to remove the two bantam salmon faverolle pullets that are living with them. Please- silkie roosters are different from other breeds. Please don't give me an answer based on your experience with other breeds. Silkie roos are famous for getting along with one another. Thank you!
