I am going to phone the vets anyway but wondered what you guys thought as well. Storm seems to be drinking more water than normal - almost twice what she used to. She is fine in herself. Bit worried as it's not hot weather! I did wonder if she was not drinking much in the field - but Chloe is not drinking to excess and if they were being fussy about the water buckey then I would expect both to be thirsty. I've changed their water in the field yesterday just in case something was putting her off. Anybody know what it could signify? Quite worried as she was so ill this summer - and we never did really get to the bottom of it.
