Last week I posted photos of 2 nest mates on FB asking if they were cocks or hens. I thought the 222 was a cock, but the men from Pro Patria made me doubt. A tip from Jos Nijman led me to send some feathers to Gendika..and sure enough.. both Pietertje and FB friends Cees, Ben and Bert were right after all
