Why would over half of my 4 month old guineas suddenly decide to settle down for the night in the wood chips on the floor of their coop, after several months of them all happily perching side-by-side on the two highest of the three roosts that are in the coop? The three roosts are not close together. There doesn't seem to be squabbling going on, forcing those to stay on the floor. They just settle right down in the chips when they go inside for the night. Guineas.....
.....go figure, right?
