The regulations apply to hen eggs marketed within the Community. They do not apply to eggs sold
direct by producers to the final consumer at the farm gate or locally door-to-door *. However, to be
exempt the eggs must be from the producer’s own hens.
* Producers with up to 50 laying hens may sell their eggs at a local public market, provided that the
name and address of the producer is indicated at the point of sale. Producers with more than 50 hens
must also stamp their eggs going for sale at a local public market with a producer code.
Producers with more than 350 laying hens must be registered regardless of how the eggs are
marketed.
That is taken from the SGRPID website for those in scotland....Defra's says pretty much the same.
