I'm looking for personal experiences in regards to adding a mature rooster to a flock of all hens. My girls are a mix of breeds, the older girls are about a year and a half old, the younger ones about 6-7 mths old. I had had two roosters and my experiences with them were, let's say unpleasant when they hit the one year mark. Dearly missing the dynamics of having a roo in the flock and knowing I wouldn't be able to independently replenish the flock, I decided to poke around the SPCA shelter and talk with them about if they had one that fit what I was looking for. While they have a handful of gorgeous roos, low and behold it was the boy I found the ugliest that was the one recommended as their best fit for what I was looking for. I figure going the route of the SPCA I stand a better chance of knowing what I'm getting, roo disposition wise. The boy I've got the appt to go and meet is 3yrs old. I've been reading up on how to add a rooster to the flock, have personally added new pullets successfully, but would really love some experienced advice. Or even advice in what to look for when I'm at the SPCA and deciding which boy we'd like, breed isn't important. While I know it's recommended 30 days of quarantine, is it possible to maybe make it less somehow 'cuz the new guy will have to stay in the house in a big dog crate.
