I'm fairly new to ckns and I currently have 2 roosters (brothers) and 3 ducks that are use to being together. In the next day or two I'm getting our first batch of chicks to raise. We are getting 15 hens and 1 more roo. I was reading up on intoducing new ckns to an existing 'flock' and am not sure if this will be different. Much of what I was reading was about alreading having hens, which we don't have. I know there is a concern about the new roo being introduced, but the girls should all be fine, right? From what I read there could be new squabbles with the roos I already have too. Should I expect there to be problems w/the roos and the new girls? I also saw that you should wait till they're a bit bigger/older to introduce them but does this apply since there aren't other hens? I'm just trying to figure out how to handle things and be prepared (physically) w/our set up to have them seperate for awhile if need be. I don't intend on keeping chickens in my house past 2 months! The ducks and roos I have free range mostly. We have the coop done which the boys use now and the ducks have their own house. I can put the boys back into their prior smaller housing and let the newbies have run of the coop and run while the others free range. They are big boys too (light brahmas)! I want to have the least issues as possible. Getting them this time of year w/the cold coming is enough to worry about...I don't want a bunch of fighting issues. Thanks for the info!
