No idea. But if she wants to sit in the egg why not let her.I’ve put the egg in the coop.The female came running when she saw her eggy.they’re in the coop now and as far as I’m concerned she’s a broody.But I’m not sure if the egg is fertile.I don’t want to depress her by giving her loads of unfertilised eggs.pls can someone show me a rare technique for understanding the difference between freshly laid fertilised and unfertilised eggs?i already know the candling technique and it’s gonna take days but I’m leaving my grans today since the caretakers will care for my chickens
