I have a 3 month old silkie bantam which had the sneezes a few weeks ago and recovered fully. She is usually lively but today her eyes are shut. They are not crusty, inflamed and there is no discharge from them. She just looks like she is asleep. I lifted her out of the hen house to try and wake her a bit and she made no attempt to open her eyes and just bumped into things. She was perched. She wont eat or drink. Im in the uk, clocks changed Sunday. Any ideas?
