I have some girls that lay early in the morning, some that lay in the middle of the day and some that lay late afternoon... I have seen my RIR girls in the nest boxes before 9 and another day it might be just before dark! I have a Barred Rock who is always in the nest box around 9...she is the only one that seems to have set schedule.. All the others lay at different times..
I get a bantam egg first thing in the morning along with my old lady chickens egg, both are laid in the coop before 9am. Then I get my columbian rock cross egg beside our porch in mid afternoon, between 1and 3pm and around the same time one of my jersey giants lays one on the front porch. Then sometime between 4and 5pm my other bantam lays in the coop and my other jersey lays in the coop
usualy all around the same times every day... unless they skip a day then it all differs, but has been the same since the nice weather hit
Mine lay all different times of the day. Most of them before noon but I always get some later on in the afternoon also. Just when I think I have their schedule figured out something changes & I'll go out to empty nests in the morning & full ones in the evening??
