Picked up some eggs from a local breeder and set them into my incubator last night. However just out of curiosity & wanting to check the fertility- I crack 1 egg open. The white was pretty gelatinous and thickly congealed onto the side of the egg shell. Broke another egg, and same thing. What does this mean? Breeder had said she collected them in past 3 days, had them in a turner, so I've gotta give her the benefit of doubt; but it's so odd- figured I had to ask.
