I bought some eggs off ebay.... the ad states: This auction is for Black-Sex link-AKA Black Star Chicken Eggs ready to be placed into your incubator. We have hatched out several batches for ourselves and have extra eggs that we can sell. When I opened the box the note states: Eggs are kinda small since the pullets have only been laying for about 3 weeks. If this is the case, how have they hatched 'several batches'? Please weigh in on this, I am new to shipped eggs and want to play by the rules, but, this just doesn't pass the smell test.
