I do understand how hard it is to have to rehome a little unexpected male.
I would like to offer a suggestion not about the little guy but for your flocks future well-being.
Since you only had 3 and one cannot stay that leaves just 2. It is hard to have just two since they are flock animals. If one of those happens to pass away you would have a single bird. They can really struggle as single birds.
Since they are quite young it is a bit easier to introduce new ones than it will be when they are older. It may be a good idea to look for 2 similarly aged pullets to add. If you do add you will need to do so carefully so they don't beat each other up. There are a lot of great folks on here that can help with what steps to take for a successful integration.
Just a suggestion.
