Yesterday i decided to add a couple leaves of real nice seedy hay into the big pen i have for my Coturnix. Today when i went out to tend them i heard them making these odd little sounds . When i looked into the cage i see a bunch of them over on the side that has the hay all fluffed up into a "mountain" ..they would run up to the top of the hay pile, make a silly noise then sort of slide -wiggle on their chests down the mountain, making more silly sounds as they went. it was soooooooo cute . The whole thing brought to mind children sliding down a hill in the snow on those "flaying saucer" things in the winter... Has anyone else observed such silliness from their quail?
