How early layer feed?

[Auscal]

Ok, so I know that "ideally" layer feed should be started at 18 weeks, or first egg - whichever comes first.

That said, would the following be too harmful?

Chickens are 14 weeks old, they will have starter/grower crumbles only till around 12 o'clock, they will then have only layer pellets available (in a yard with older birds) till around 7 pm, when they will then have access to the grower only again. They are also eating grass, weeds, bugs etc. This routine will make my management much easier, provided it is not going to do any major damage to the youngsters.

That should be fine, won't cause any damage. Major or minor.
