My SILKIES flipped head over heels today over" CHEESE"! I never saw them like this before it was a circus! Singing,humming,dancing ,grunting, squawking,grabbing,running....they actually had to nap from it all. Usually when I give them their healthy supplemental food they will freeze up ,all of them if it is a new food,until I offer by hand or a brave soldier tries it, then others follow suit. I have my own carnival and do nor need to go anywhere else for "cheep" entertainment!
