Generally it does get less awful. Young roosters are like teenagers and they are full of hormones and just getting the hang of things, and young hens aren't yet used to the idea of submitting for mating, so it can look pretty ugly. As the roosters get older, their hormones settle down and they become less crazy about mating. They dance for the hen, and the hen will squat to give the rooster the go ahead, and mating is entirely consensual. That said, there are some roosters that are just terrible to hens and always grab them and mate way too much and generally make the hens miserable. Those types of roosters need to go. My dominant rooster keeps the young ones in line and will not allow them to mate with a hen if she is squawking and putting up a fight. He will run right over and knock the juvenile right off. So it does usually get better, but a small percent of roosters never treat the hens well, and those should be separated or gotten rid of.
