14 weeks I thought is pretty early on laying. My leghorns started laying at approximately 17 1/2 weeks which is considered early. I read on most articles that the average laying ages are 18-24 weeks. My first batch of layers were all laying by 22 wks (the heavy breeds)
I switched them to layer feeds when my leghorns started laying and offered crushed oyster shells on the side.
Majority of their combs became really bright red from pink and they have started making melodious tunes, squatting and hopping to their nest(almost restless) for few days before eggs appeared some on the floor some in nests, some under the roosts. I guess they laid while sleeping, some were perfect but tiny , some had no shell. This went on for few days to a week. I didn't open their nests to be used until 17th week. I found some ceramic very lifelike eggs from our local store here and it did encourage them to be consistently using the nests. Just be watchful since if they happened to break an egg, some of them will develop egg eating habits. We collect eggs 2x a day before we go to work and when we get home in the afternoon. I've noticed majority of them are early layers by 10-11am all had laid eggs, some occasional afternoon late layers are rare by 5 pm other wise they skip for the following day. On Saturday and Sunday's we collect eggs more often so they won't step on them to get soiled, we don't wash our eggs so not to lose the "bloom" protective coating. Hope this will help you and enjoy your fresh eggs. My family and friends
