I have 24 chickens between the ages of 5 months and 2 years old. My 2 year old laid 2 eggs just after i got her and she stopped. I have 6 that are 8 months and have yet to lay. My 5 month old girls i think are still too young to lay. I also have 10 ducks and 4 little guineas that share a coop at night with my chickens. During the day they all along with 2 goats and a pig get the run of my yard and get put up at night. Someone is always home with them so we would know if they were laying in the yard. Any advice will help.
