we've had our 4 year old donkey, Barney, since last april.....he was 'dumped' on us after 2 good friends got divorced/lost their house etc...all the animals were brought to us. anyhow he's lived outside all his life......through wind/rain/ice/snow/sunshine. never been a problem. he has a nice little stall out in the field to keep him high and dry and warm. now yesterday he didnt come out of his stall. the field is still covered in frozen snow so i thought maybe he just didnt like the crunch under his feet. today the sun is shining and the snow is melting, yet Barney is still in his stall.i went out this morning and he was lying down in the straw. he wouldnt get up, i had to push him to his feet! he usually pushes you away if you comb him but today he's just stood there, not moving. i edged him outside to try and encourage him to drink. he wouldnt drink (and as far as i can tell hasnt drank all morning, the water trough is untouched) he's munched through his hay and pellets though. i left him standing outside his stall in the sunshine , that was 5 hours ago. he's still standing in the same spot now? as far as i can tell he hasnt moved. he hasnt brayed either today, normally you can hear him as soon as he see's someone walking by, but not a souund today. theres something not right but i dont know what? he's pooped fine...all looks normal that end. one of his back hooves are a little overgrown than id like but the guy comes in 2 weeks to do them again (they get done 3 times a year) i dont know what could be wrong? i will be honest and say i know very little about donkeys, we got kinda thrown in at the deep end with this. but im worried about the fact he was lying down, the fact he didnt push me away, the fact he's in his stall at all in the day time! (he's normally over in the corner of the field watching the sheep next door), that he hasnt moved in 5 hours and he's not drank today any thoughts?
