I can see what you mean. There is definitely a disc of lighter yellow around the white. Hmmm. I would pop some in. Interesting.Looking for advice from more experienced hatchers: Is this Buff Orpington egg fertile?
We bought chicken hatching eggs this year because we lost our rooster last summer. So I was caught a bit off guard when I saw this when making breakfast last weekend. I haven't seen her fraternizing with our Guineas, but they all free-range so I suppose a cross might be possible. If the eggs look fertile, I'll collect the next 3-4 and stick 'em in the incubator to see what happens. Guins
