My guinea hen hasn't laid an egg in the last year and a half that we've have had her. At least non that we've EVER found and she stays close to home. This past spring we added some chickens to our brood, a barred rock rooster was a surprise and that rascal is taggin every bird he can. About a month ago our guinea went broody. We counted about 18 eggs under her this morning. We've moved her into a secure area and she is still on those eggs. My question is this: Can our barred rock rooster mate with our guinea and produce fertile eggs or is my guinea hen just nuts?
