We're down to 4 guineas from our original 6 keets this spring. A few weeks ago (the guineas were all still roosting every night in the chicken coop) when doing my nightly head count, I only saw 3 and figured another had met it's demise. Well a few days later, I chanced upon a guinea nest after watching our dog waltz into the brush and come out with an egg... Turns out #4 has been spending it's time on the nest Now I must admit, I'm still not sure our male/female ratio or IF we even have any males... I try to listen to the calls, but I'm not home usually during the days and they quiet down quite a bit in the evenings. I did crack open the egg the dog had and it appeared through my untrained, non expert eye that it did contain the "bullseye" I would associate with a fertilized chicken egg. Now my question is this; would guineas be dumb enough to sit on a nest of unfertilized eggs? (Assuming of course that they know better than I whether a male is amongst them) Or in another way; can I assume the eggs are fertile by the determination of the bird on the nest, or is it possible this guinea could be completely wasting it's time and putting itself in unnecessary danger? I don't have an incubator, nor will I be buying one any time soon, so an option of moving the eggs to an incubator is not on the table. However, I'm willing to let nature do it's thing if it wants. Thoughts?
