My Rooster has started trying to mate with my hen who just started laying a week ago, and in fact, this is the only hen he'll attempt it with and only started to the day before she laid her 1st egg. My question is, how long is the act of mating because it's literally just seconds and then he's off. Is he still trying to get the hang of it? Or is that all it is? They are both very new to the "mature" chicken ways, but have grown up together. Obviously this is my 1st time witnessing this, so any advice regarding fertility chances and all the details are welcome.
