It can take a rooster soem time to mature.A rooster isn’t fully mature till two years,not saying yo can’t start picking out good from bad early on,because most roosters by a year have shown you just who their gonna be,and that’s that.I can say from experience,once he gets a certain age (8 or 9 months)he probably will be doing things a rooster would do.Teenage months are for purely practice,but that’s not saying he won’t step to the plate earlier on,most males do.Not saying breed has to do with any thing,but I typically hear polish are a soft breed,so he may not be perfect for a free range flock:
