Most definitely! I have one or more roosters at any given time now, but before that, my hens would range further and that is also when I lost 1/2 my flock. I've not lost any since I got a rooster.Something I've noted with my flock that includes a rooster vs a friend's flock of hens is that his range much further whereas my rooster seems to keep mine tethered to within a few hundred yards of the coop. Has anyone else noticed this?
I do have an even more recent addition, and that is 2 guinea fowl that are now grown. I believe they are a respectable alarm for the flock as well.
Yes, the guinea are noisy, but it doesn't bother me. They can be aggressive towards the chickens, but so far it has been necessary to find them a home. I think I may have 2 boys, too. Only say that because I've not see them "do it" or lay an egg. LOL
