First of all I'm so if I posted this in the wrong section, but I thought that this looked like the appropriate section. Anyhow, my mum wants to know how we can tell if our hens eggs are fertile eggs. I tried to explain it to her but she wants an expert telling her. We have 3 hens and one rooster, we have only had the hens (1 laying, 2 point of lay) for a few days and there has been a far amount of mating going on. My mum is worried that because of this we could pick up an egg crack it or cook it and a chick falls out. I told her that that is highly unlikely. So how can we tell if the eggs a hen is sitting on are fertile.
