So I am a little worried about introducing my new flock to my old one... I rescued 15 hens last year along with a rooster. I had my trial and error and hatched some babies, I did a lot of reading about how to introduce them soooo... I built a pen in the coop with the baby birds surrounded with chicken wire so they can all see each other.... Then the other day all the hens were outside except one and so I left the door open in the coop thinking everything would have been fine since the rooster was outside and it was just the hen and the babies... Now they were hatched some in late November some in December,.. So there not baby babies lol... But the hen started a fight with one of the smaller hens and I actually had 4 out of 6 being new roosters... Numbers were not in my favor lol.. Now I planned on getting rid of my older rooster he is mean to say the least and my new roosters love people... Needless to say the hen started fighting with any of them that jumped out and my baby roosters were not happy and became kinda aggressive towards the hen... They weren't mad at me for breaking up the chicken fight but I want to avoid this as much as possible... Any advice??
