One of my golden comet hens has not been laying right for the past couple of weeks. She either doesnt lay at all or onky lays shell less egg yolks that are very runny and the clear liquid is bright yellow. They are fed regukar laying hen feed plus oyster shells and are turned out 2 times a day to free range. This morning i went out to collect the eggs and i found this Egg. Is there any suggestions on what i can do to get her to lay? And is this egg good to eat?
