Rosie,
I've had to rehome a number of girls over the years because of the turmoil they created in the coops.
Just like people some birds are "difficult".
I re-homed a gorgeous cuckoo marans last week because she was so load, unmanageable and unfriendly. Soon as she was gone my other 7 settled into a wonderfully quiet pecking order and no more pacing....and the loud egg announcements are over....some birds need a new home to ne comfortable.
Re-homed a blue cochin last fall for the same reasons. She was just tormenting the other birds and terribly bossy and noisy.
I like the peace and quiet I finally now have.
My broody snow cone's eggs are due to hatch in 6-7 days!
My leg bar (7 weeks old) is hanging out with her and for some reason she is allowing it.
