My first roo was actually a trade; I got him and 2 pullets at 15 weeks old. The gentleman I got them from is a long-time member here, he told me to just put them in, and it would be fine, but after everything I had read on here, I put them in a separated area in site of my ladies. After about 3 hrs it just looked like they wanted out so bad, so I opened the gate and took a seat to watch. There was minimal interaction and for the most part everyone would go take a look, maybe throw a peck, then go about their business. After a week you'd never have known they were newbies, and Klaus turned into a perfect gentleman. Now I will add that I have well above the minimal space recommendations, and I'm sure that played a big part. My current roo was hatched and raised with the flock and is a very good boy also.
