I suspect that the defra figures are meaning "farm gate" as in the price a farmer gets at the point of sale rather than the price of actual eggs sold at his farm gate, and therefore are not referring to small producers selling direct to the consumer. There's no way that defra would be able to collect that information and they probably wouldn't want to anyway.

Aha, I think you are right.  That makes more sense.
