Amazing what a "time out" can do! Little Miss Nugget spent a night and part of yesterday sequestered from the other two chicks. Every time I would put her back in with them she would start pecking again and I would immediately remove her. I also tried the "hissing" recommended upthread - maybe that was the magic touch - by yesterday late afternoon she seemed to have settled down and they all three spent the night together and no one seems worse for the wear this morning. Looks like the little RIR gets to stay. Whew!
Really appreciate BYC - not sure we would have waited it out if I hadn't found this thread.
