My roosters are fighting

[Gossie]

I have 3 roosters. Two of them keep fighting with eachother and neither one gives in. One is a giant coronation sussex and the other is a black silkie bantam. We separated the bigger rooster in a cage that we put in the coop. Will they ever get along? Is there anything I can do to help them get along?

I would worry about injuries, especially with such different birds. How old are they? In general, more space, more waterers and feeders, and more hens helps things. However, some cock birds just won't get along, and either moving one elsewhere or two totally separate coops are necessary. Mary

What is the size of their current enclosure and how many birds, total, are there in the group? You don't really say whether this is a bachelor group or if there are any hens in the mix. The silkie is at a distinct disadvantage when it comes to the fighting so you definitely want/need to get things sorted out ASAP.
