Ive had a small flock of Barred Rocks and was looking to get a broody hen so I posted a add on Craig's list. With in a few days I got a email from a gal who lived about a hour away saying she has a young broody Mottled Cochin Bantem. I did my Re search learned they are very broody and great mothers so I picked her up for $25. Being small she was real intimidated by my flock and has been welcomed by my roo but my hens thrash on her bad she is no longer broody nor likes to be around the flock. So I figured Mabey I need a larger broody hen and left my add on Craig's list. A few days go by and I got a call from a guy saying he lives in my town and has a broody Welsummer that I can have free of charge. Same exact thing my hens want to thrash on her. She is no longer broody and won't go around my flock. Now my Cochin Bantem and Welsummer stick together and just want to stay hiding in the hen house. I'm not wanting two flocks to co exist what should I do? I understand the whole pecking order but these new hens are so scared they don't even try defending them selves or establishing a place in the flock.
