We have two roosters - a Buff Orpington who is about a year and a half old, and his young, three-month-old son who is a mix between him and Ameracuana. I have read in multiple places how to get two roosters to get along, and I think that these two will do so quite well. We have thirty hens, the chickens are free-ranged, and both father and son have never shown any sign of aggression towards us or other chickens. (Actually, our big, tough rooster is scared of baby ducks, so I think we'll be fine.) However, I read somewhere that if they are away from each other for too long that, when they're reintroduced, they'll forget that they've known each other and start fighting or something along those lines. I took the Buff Orpington to fair this year and I would like to take him again next year, but that would involve him being separated from his son for a week. Is there anything that I can do to make the two of them get along when we return?
