Same here....some days my hairy's are huge others not...mine not quite the colours yours have. My first 'specimens' over 20 like yours....My Hairy's and Rhodacs, both over twenty years old. The hairy are funny. Some days they are four inches across and some days six across. When they are big, they look just like an elegance.
I do love em, as they grow, but don't overtake. I actually have a leather that has decided to bury its head into the colony last month or so, likely a goner....
