We had a dozen chickens that were split up after a few weeks together. They are now all 6 months old and live in two different locations. One group has been laying for a few weeks now but the other group hasn't laid a single egg yet. What is up with that? Shouldn't they lay pretty close to the same time? Also, will a watched hen ever lay an egg? My wife, kids and I are checking quite frequently now trying to be the first to find an egg. Could this be giving them some pause before letting them go?
