My Hen has been laying eggs for a few months and she hasn't gone broody yet. So I stopped collecting her eggs and just want to know what will trigger her to start sitting. What will make her hormones kick in to start incubating? Is it the number of eggs? Is it when she finish laying a clutch? Is it the light, humidity, or temperature outside? I know she has laid more than a clutch but I have been collecting them. Well I put in a nest box in there cage and I am not collecting the eggs. Is it the site of 7 or 11 eggs going to trigger her to sit?
