My new horse keeps escaping (please see other recent thread) and has got into the barn where the chicken feed is. He has somehow managed to knock the lid off the chicken feed bin and managed to eat about a 1/4 of the bin. By bin I mean like a big blue round tub that stands around my shoulder height and i'm 5ft 3in. Also he managed to eat about a third of a bale of hay last night. I'm concerned firstly about the risk of him colicing and secondly i've been told that chicken feed is highly poisenous to horses is this correct? When I went to check him this morning before work he was stood still in the field and looked uncomfortable. I couldn't see any obvious signs of colic but I bet he has a major stomach ache. Please could you advise me what to do? I was advised to go by some bran and mix it with warm water. I'm at work now but my mum is going to keep an eye on him today.
