This is my second year of back yard chickens and we have run into a bit of a problem. We keep 5 ducks(3 female,2 male), (4)2 year old hens and (6) 9 month old bantam hens all together and I’m only getting one chicken egg a day! The chickens roost in their coop and the ducks have a little house inside the shared run. We provide dry food, of which we have switched brands a couple times hoping it was the feed.they all free range throughout the daytime in our property with lots of vegetation and access to water. Does anyone have any suggestions on things we can try? I used to get 4-5 eggs a day from the older birds and have gotten none from the younger. Help!!
