Hi, we are getting frustrated with our 5 chickens. They are about 16 months old (1 Americauna, 2 Rhode Island, 2 Barred Rock) and they were great layers through June of this year. We're not sure what happened but for the most part, we get 0 eggs per day and occasionally 1 egg. They get fed organic feed from local feed store and we also have been giving oyster shells as suggested by this store. They get plenty of water and food and are basically spoiled and treated like queens. They don't seem stressed and appear healthy. We let them free roam every evening and they have even caught 2 mice this last week! What is odd is when we open nesting box, they all seem to lay in the box for 1/2 hour or more each day but they don't lay eggs anymore. Only the Americauna is molting, and no eggs from her since early July. Will these chickens start laying eggs again? Thanks in advance.
