so i have rooser who is new to my flock (he is 13 months old, i was told) and i am just wondering when he will start doing his "job" such as staying with the hens-right now he sometimes stays in the pen while they roam and he has been going to bed about an hour before them, also fertilizing-i haven't seen any "action", will i? or can i just assume the eggs are fertile at some point? he has been with us for almost a week. thanks!
