I have a year old rooster that has 8 one year old hens in with him. I got an 8 year old hen from a friend about 3 weeks ago and my roo won't stop beating up on her. He won't let her out of the coop and will even go into the coop to peck at her if she comes to close to the doorway. She won't come out of the coop unless I am there, she immediately comes down to eat/drink and even if I let the others out to free range and close the pen door so it is just her in there she goes right back into the coop. The other hens have pretty much ignored her. The first few days I left them all in together so she would get used to being here and then I opened the gate (free range during the day) and she disappeared. I found her the next day in the woods. Then I thought I would let all but her out to free range for the last part of the day so she could have time to come out and eat. This last week I finally made her an area that I can put her into during the day and then put her into the coop at night. Get up in the morning and he won't let her out still. I have been doing some reading (BYC rocks) and saw that everyone that has a mean one will seperate the mean one and later reintroduce. I was wondering if I seperated the roo from the flock, do you think it would help? Has anyone had any experience in this type of situation? I only have the one roo and would like to keep him to protect the hens when out free ranging. He has also started trying to be dominant towards us (me and my son), I have been following some of the recommendations on this site although I have yet to pick him up and carry him around. If he is determined not to calm down I will get rid of him as I have younger kids. The hen is old, but she is the calmest/sweetest of all of them. BTW, my friend got rid of her for this same reason. She has 3 young roosters and only one was acting this way towards this hen. So, any help or ideas would be appreciated. Thanks!
