Are you comparing to home raised hens or store chicken. There's no difference in taste and smell between home raised males and females. The males are a bit scrawnier. If you raise cornish cross they are just like store chicken. My rule for non cornish cross is low temp for a longer amount of time. Think smoker or slow cooker instead of grill. I raise pigs and have raised other mammals for meat, including intact males, so I know what you mean by smell. Not a problem in chickens.I feel like first it’s wanting all eggs to be fertilized. Then all eggs to develop properly. Then to make it to lockdown. Then for all to hatch safely and without issues. after all that stress then it’s “okay who’s a girl?”
(For those of you who have eaten a rooster before do they taste or smell weird/different compared to a hen?)
