So our school has some chickens that they have raised from eggs, which is wonderful. There are 3 chickens and one cockerel. The chickens have started laying eggs, which is great as the kids love it, but how do they know if the eggs are not fertilised? I would ask but I'm always the one to ask these sort of questions and I don't want to be the parent that is always kicking up a fuss. But I'm concerned about the eggs being fertilised as they are being sold at the school to the children/families.
