It's been awhile since I've been on, so Hi again. Any way, now that my hens have started laying I've noticed that some of the eggs have a yolk that is almost solid. The whites look normal, but when we break the egg in a bowl, the yolk stays in a round shape and when you stick it with a fork, it doesn't break. I was wondering if they may have froze or if it's something else. We both work, so we check for eggs in the morning and again when we get home in the evening.
