thanks!
well, im on a farm where im the only person and only horses, theres been lorry drivers coming up the farm to deliver potatoes etc, and last night i actually noticed an apple tree just opposite the stables, i think its prob one of the drivers thinking they are being nice, and prob didnt overfeed them. The apple i did find on the floor so maybe rosie decided she didnt like them! theres also a footpath cutting through the farm so it could be a walker i suppose.
i was just a bit worried as i do not like people feeding my horses treats that i dont know about! its really worrying as i only read an article the other day about a horse on a carefully restricted diet dying of colic due to passers by feeding him lots of treats!
