Ok this is really gross, some of my eggs have what looks like pieces of hamburger in the egg white part. Only one hen was laying eggs like this...now two of them are. Some of the "bits" are teeny and some of those are as big as a lentil! It's just nasty. I dont know what it is, or what causing the eggs to have these weird nasty things in them. It's been going on several months now. I wormed the hens when I first noticed this, fearing the bits were worms or something. I am totally clueless.
