can i just say, if its a public footpath you are not allowed bullocks on the field if that field is open to bullocks crossing your path, if you do find this has happened a) contact the farmer and remind them its a public right of way even if it is their field, contact the council or countryside dept whatever is needed to let them know this has happened.
cows dont normally come within arms length of you if there is no fence between you, if you had walked towards them theyd have backed off, good idea walking backwards mind.
after my uncle having a near death experience (and he worked with livestock for a few years) landed on him after cows and a bull charged last year, had brain surgery and well il not put you off ya suppers but he is lucky to be alive and looking not much different to that he did before the accident but i dont think my aunt will be letting him drive the wagons again anytime soon, but i still love cows
