It is a well-known fact that donkeys are not waterproof so, when it snows, you must take the same care of them as if it were raining. Make sure you keep the entrance to the stable clear of snow and ice as a donkey can slip just the same as a horse. It’s essential to make sure the water supply does not freeze up. If it does then you need to get fresh water from somewhere. In freezing cold days put a little hot water in their drinking buckets to take off the cold otherwise they can get dehydrated from not drinking.
When they are out watch that snow does not ball up in their feet. Best check their hooves for balled up snow. If you have to take your donkey over icy patches, don't hold his halter too tight. Let him find his own way and he may slide but won’t fall. If he does fall, don't panic! Take your time, speak to him quietly and he should manage to get back up again quite quickly. However, check to ensure he hasn't hurt himself.
When donkeys go out in to the snow initially it's great fun for them to tear up and down, push their noses through the snow like a snow plough, roll and snort etc. It’s OK for a short time. Let them have their fun but bring them back in before too long. If you are away all day you’ll need a good rug.
Enjoy your donkeys but don't let them get too cold in the snow!
At my place it’s been -6-10oC for days and the ground is frozen hard. The entire yard is like a skating rink and as the donkeys have to come down a slight slope to their paddock they are staying tucked up in their stables with mangers full of hay and bedded in straw. All that sticks out is their ears!
All the outside taps are frozen so the only hard job is carting water from the house and, it seems, the more you carry the more they drink...Well, all for the donkeys.
