I have a rooster and 5 hens in a portable chicken tractor that I wheel around the yard. About every other day, I let them out to run around and explore for a few hours. During these times, I've noticed Mr. Roo doing his job. I'm realizing that I've NOT seen him after the hens while they're in their tractor. Should I assume that he's not interested unless they're allowed to roam about? I'm pondering this theory b/c this last batch of chicken eggs isn't hatching--they don't look fertile. When I candle the eggs, the light seems to shine right through the lower 1/3 of the egg. And I remember that I wasn't letting the chickens out much before that collection time.... If roosters DO behave as I suspect, what else do I need to know about roosters??
