My chickens turned 1 year old in March. They have gone from producing 12-15 eggs a day to 2 to 5 at times and then some days 8, but never as before and they are 15 chickens! My neighbor said they are molting, they did lose some feathers about 2 months ago, but now it looks like they are losing some again. One chicken went broody, so she does not make eggs, but what about the rest? they are eating like pigs, but can't understand what is going on.
