I have 3 Bantam chickens, 2 hens and 1 roo. They are just over 1 1/2 yrs old, and I raised them since chicks. The girls appear to be very healthy, but stopped producing eggs. They were molting when I first noticed the missing eggs, then the shorter days, then colder days came, and still no eggs. I keep them in a a 6 ft x 12 ft pen with a clear roof for sunlight. In addition to the regular layer feed, I give them treats of banana, yogurt, cooked eggs, uncooked oatmeal, and occasionally, some super worms. I've read up on it, and still baffled why I get no eggs. Do Bantams stop laying at this age?
