Hi everyone in chickenland! I was wondering if you all know....I have had my maran hens seperated out for about 3-4 weeks now, I want to add the maran rooster in to collect fertile eggs.......have I waited long enough to "clean out" the maran hens? If I add the rooster back in now, how long before the eggs are fertile with his genes? The only thing I can think of is to crack eggs and look for the "ring" thing that means its fertilized? Thanks everyone!
