Let him mate her.But what if he injures the hen ? I don’t want the hen to suffer, I have read they can even leave scares on their backs … she is a young pullet she have not even laid an egg yet. She just started to squat last week and he already jumped on her 3 times, twice I chased him off and once my older hen ( the head of the hens came to the rescue and chased him off )
It's not an issue unless there's not enough females for him to "spread his love".
