I'm so excited! How do I figure out who laid it? I have a Black sex link, Brown sex link, Australorp and Silkie. They are all 20 weeks and 2 days old. I THINK it was my Black sex link because she has the biggest and reddest comb of them all. The Australorp has a tiny comb still and the Silkie is way to young. The Brown sex link is the only other probable one. Is there any other way to tell? The egg is half the size of the eggs we get from a local farm.
