I have 11 hens (RIRs and Production Reds) which were laying 12 eggs every two days. These chickens are only about 6 months old. We thought we had 12 hens and one turned out to be a rooster. We had a rooster that got nasty and turned him into chicken and dumplings...allowing the red rooster to be king of the hill. Now the hens aren't laying...an egg a day for the last two weeks. We killed a chicken snake in the henhouse two weeks ago but that has never before affected my chickens laying. No, they are not molting. Suggestions as to what the problem may be? The weather is perfect and they have a closed pen to keep out predators.
