Here's where mine go. They are among the flock and can still interact through the wire. The one in the picture spent about 6 months in there and is now one of the flock roosters, he went in a jerk, and came out a nice polite responsible rooster.
The one that is currently in there has been in there since spring and will be released in the next week or two to see how he does.
I always give mine a chance first, most need to mature, 8-12 months, depending on breed, yours should mature quicker because he's a smaller breed. I do wish you luck. If he doesn't work out well, I recommend bantam cochins and barnevelder as being more gentle roosters.
