So locking Manny out was a two person job. An hour and a half later, Meanie and Sheba are still having nothing to do with Eenie. Meanie remains firmly ensconced on the top roost. She spent the first 45 minutes or more screaming at the top of her lungs. Sheba never made a sound, ate all the treats, went to the nest, came back out, ate the treats I put to try to lure Meanie down, and joined Meanie on the top roost. 
There were two minor dust ups at the very beginning, when Meanie jumped down on Eenie, who promptly handed Meanie her tail-feathers! I no longer fear for Eenie from the hens! She can clearly take care of herself.
So, in a few I'll reunite Manny with his girls. I'll put Eenie up with the chicks if that's what she wants. We'll see how it goes there. I guess we'll try again tomorrow.
