I have 5 pullets turning 18 weeks next week and have not laid their first egg yet. (I have 6, but 1 little lady has been laying for 4 days now.) I have 3 golden comets and 3 rhode island reds. My question is when should you start the transition to layer feed? At 18 weeks or when they lay their first egg? I saw some conflicting info on google, but I would feel more comfortable hearing from you guys! :D
