My hen-only one has been sitting on eggs for a few hrs at a time. I dont want any hatching, but in a few months. If you dnt have to many hens to one rooster then you shouldn't have any issues with fertility. What you should think about is letting the hens/rooster get to know what they are doing a awhile: let the hens lay and the roosters get the hanky panky figured out, maybe a month's time. Then collect the eggs and crack them open and see if you see a white bulls-eye on the egg. That will tell you the eggs are fertile.
I wouldn't eat the roosters till your hens start laying, that way you will know which one is the best rooster. Also by letting the hens lay for awhile you will be able to observe which one will be the best broody. All the ups and downs want be smoothed out over night, by giving them a little time to figure out their life's mission will get you going down the "farming " path without very little issues. Have fun, enjoy!!
