Selling 2x 24 small eggs for the squire bunny custome. 500fg for one set
Also selling 5 small eggs that are leftovers. 21fg per one small egg.

This is your chance to get the bunny custome for squire or you can wait till next easter and farm them yourself. Your choice.

one question: ive got big eggs left, do they count as 2 small eggs or something like that?

No. Straight from wikia
