Next year i would like to take my 3 DDs (6 and 2x4) on holiday to a farm, the sort where they get to help feed the chickens and maybe even ride on tractors. i live in cheshire so am looking for ideas a bit closer than cornwall (although if we have to go there we have to go there). i don't mind camping at all. has anyone got anywhere they can recommend? pref not too expensive!
