Ok so I have 17 hens and about 5 roosters, 4 of the roosters and 5 of the hens are almost 5 months old and have grew up together, the other rooster is about 14 months old and he is a game rooster. Six of the hens are 7 months old and the other 6 are over 2 years old. So when I first introduced the young roosters and hens when they were about 4 months old and all the older hens used to pick on them but now since the roosters are older and bigger they are higher in the pecking order than the hens, there are 2 hens that are 2 years old that are very scared of the young roosters and run away from them which causes the roosters to chase them down and forcefully mate with them those 2 hens are very frightened and dont go near the roosters much, but when the roosters mate with the other hens the hens dont run, they just let the 1 rooster mate with them and then calmly get up and leave, but with the other 2 almost all the roosters will mate with them in one sitting and I think this is because they run away. But my older game rooster doesn't do that with any of the hens even if they run.(Keep in mind that the game rooster is still the dominant rooster but is nice to the other roosters) I think the roosters do this because they have just reached maturity and will learn to calm down and not over mate and abuse the hens. Will they stay like this or will they grow out of it and/or will the 2 hens learn to cope with it and not be scared???
