Sorry for your losses. Cougars, yikes.Update: sadly I lost three guineas to the cougars. However my remaining six have continued to lay in the hen house at night. I had a hen go broody so I stuck about a dozen under her and am hoping for the best. Not sure if this was the best choice but the guineas did not seem to care much about them. They just laid them wherever and did not seem to be to bothered to lay on them. I will let you know if we have a successful hatch with our chicken mother.
Young Guinea Hens tend to lay eggs wherever for a while at first, eventually (if they don't choose to lay in the coop) they will pick a secluded spot out in the bushes, tall grass or other well hidden secretive spot and accumulate a big pile before they go broody on them. Sometimes several Hens will share a nesting/laying spot and the pile can be as big as 60 eggs, or more.
Good luck with your broody chicken Hen... they usually seem to be the better choice anyway, especially so early in the season.
