my mum goes up in the am [muck out & chuck out] & me & my mum go up @ nite.[bring in, ride, (clip sometimes,) groom, put to bed etc.] but mines in @ nite.
so yes, i do think you are doing enough. but do you net your hay & tie it to the fence or is it loose? if it is netted it will probably last longer. or maybe put hay @ a couple of different points in your field? just a few ideas i think will maybe prolong the life of your hay/lege lol
you cant help the ice breaking up. it's not your fault but an idea might be one of those automatic drinkers. i don't think they'd be as likely to freeze because the water moves every so often when a horse drinks. however if you cant afford it it's expensive.
ETA - anna15, how do you do it??
lol
