One chick quickly and professionally hopped down to the floor but then thought better of it and could not get back up, so we quickly improvised a ramp from peat turfs to allow easy access.
At one point Rolo the cat wandered up. Cats were our other slight worry - these chicks are not much bigger than the rats that at least one cat can dispatch so we wanted to make sure they were an out-of-bounds, off-the-menu shape for the cats. The cat came and tried to go nose to nose to a chick. The chick was bewildered and totally unafraid (a worry!) but Betty came and pecked him on the nose and he retreated in high dudgeon as only cats can.
So, we all mooched around for a while staying within a few yards of the calf house door until the hens seemed to get bored and wandered off back to the front lawn followed by William who seemed in two minds which 'flock' to marshall. The chicks and BB then strolled back into the calf house and climbed the turf ramp back into the hutch. "Our work here is done", they seemed to say. I shut the hutch door and left them to it. We gave them another run out in the afternoon, which went similarly. I guess we just keep doing this till they eventually re-join the main flock for good.
A successful excercise.
