Thank you for all of the replies i really appreciate it. Went out there this afternoon and i have 1 normal egg, 1 double yoke and another greeny/blue one. I know for a fact that one of the blue hens is laying but no idea about the others as i've not been able to catch them in the laying box. Not even sure if the bantam is a male or female lol but i think that the size of the eggs is quite different so i'm sure i'll find out soon enough. It must simply be that the 3 hens are all now laying yay
