so, sweet, mild mannered little Glinda, has gone mad! they moved into the new, improved coop last friday. everyone is adjusting well...laying in the new boxes, etc. when i let them out to roam in the evenings, Glinda puffs up to twice her size, picks out another hen, runs full speed towards her, circles around and around the target hen (still puffed up), until finally the target hen gets fed up and attacks her (screeches), after which she un-puffs, and runs full-speed back to me. she puts me between her and the aggrevated hen. things calm down for a few minutes, and the whole thing begins again with a different target. what the heck is she doing?! this is soooo out of character for her. any suggestions?
