Got this egg yesterday. Blood and what appears to be some sort of intestine or lining or membrane or something on it? Should I be concerned? There was also a broken egg in the box but I don't think it's related, I just haven't collected in a couple days. Also had 2 rubbery eggs, different days, a couple weeks ago but I'm pretty sure that was just from not enough calcium and I have provided more bowls as they dump their oyster shells out daily lol
