I have a really strange situation with my 2 EE, at least to me, being a newbie. One of my EE started laying green eggs. Cool. Then one day a giant and I mean GIANT blue egg appeared in the nesting box. The largest egg I have ever seen. I assumed it was from EE #2 and thanked my lucky stars she didn’t become egg bound. When we went to open it to see what was inside, a really big, oval yolk was inside. Inside that yolk was a thick white sack with more yolk inside. Almost like an egg within an egg. Since then (about 3 weeks) I’ve had nothing but green eggs in the nesting boxes. Some days I get 2 green eggs with one of them being smaller. So it stands to reason that both of my EE are now laying green eggs. I thought they only ever laid one color? What the heck was up with the one blue egg? Any ideas or just a weird fluke? I’m attaching a photo of the mutant egg.
