I got 3 Booted bantam hens in August, and at the time they were 3 months old. However, I got an ONE egg, and the next day, my neighbors dog got one of them, along with 5 other chickens, and I never got another egg. I am assuming the one that was eaten was the egg layer. I switched them to layers pellets at 7 months old. What am I doing wrong that they arent laying eggs?
