Report on keets:
All 25 keets happy and thriving in new, temporary coop. We moved the brooder inside the new coop and propped open the door. They started coming out 10-15 minutes later. First night they slept in the hay next to brooder, second night we had removed the brooder and they slept with most of them under the remaining (unplugged) MamaHeatingPad and a row of them outside it on the hay. Third night the higher perch (about 30 inches high) is filled with keets and remaining are on green grass below (which means they are in the part of the coop with no tarp on the ceiling, open to the sky except the hardware cloth). We got a heavy rain today but the earth drained pretty fast, though I am worried they might take a chill.
Will add more high perches. Wow, so interesting.
Further report: I was worried last night that they would get wet and cold. But when I got up it was barely light outside and the keets were back to being under the MHP or arrayed just outside it-- sometime in the night, they moved themselves. So despite what some people say, they are sensible enough to come in out of the rain (been drippy here for days).
As per so many other situations, it would seem that humans' assessment of guinea intelligence will vary with the ability of the human to empathize with the guineas' ecological niche, or not. I happen to think that every creature is a genius in its own niche.
