I found another nest, right near the barn they were raised in. It's in a tall clump of grasses. I didn't want to disturb it but was worried about rain. Hubby took an old glass patio door and four concrete blocks and put over the nest. The guineas accepted it. Yesterday, I noticed a guinea on the nest and one just outside. I came by later in the afternoon and there were two outlayer eggs. I collected those and left the main nest untouched. That makes another 15 for the incubator.
