FOUND!

at last I've found the eggs! the chickens have been wandering around for months randomly laying eggs all over the place. Meanwhile, I've been buying eggs from my neighbour because I couldn't find them....anyway, now I've found a nest and all of them seem to be good. As they were all cold, I took them but left one (marked so I know which one!) in the hope that they will decide to brood and we'll get chicks.
