Hey all. I have a Barred Rock girl (Mayflower) who's about 2 1/2 and just started laying again after a couple month's hiatus. She laid a couple normal eggs, but over the last four days, she has laid eggs with a progressively deeper and deeper spiral groove from the top to the bottom. We see odd things here and there, but I'm worried that this could represent a problem for her. Could it be a mass or tumor near her oviduct that is pressing and causing the groove as the egg descends and spins? Help/advice is appreciated! The four pinkish-brown eggs along the bottom are Mayflower's, in order Left-Right of the day she laid them. The others are from Basia (Golden Polish) and Muffet (Ameraucana). Closer-up on Mayflower's most recent eggs. Better angle to see how "groovy" they are. What do you think?
