I have 9 hens in total, 2 bantams and 7 red sex links. They all get on fine but lately the two bantams wont come out of their beds they just lay there all day on their eggs is this normal? They mind everyones eggs not just their own. I thought it might be that they are just trying to look after the eggs but my mum is concerned as they don't seem to come out even to eat. Any advice or tips welcome thanks.
