we are new to chickens, and have been getting eggs from our hens since last September, many of the eggs will have a dark reddish or brownish discoloration in the yolks, these are not blood spots, can anyone tell me what they are?
we have 3 large walnut trees in the yard and in the late summer we collect them and pile them in the barnyard so vehicles will run over them and remove the outer blackish staining shells, many of them get cracked and our chickens spend much time there, I only guess, eating walnut meat:pop
