I have a pekin duck who isnt acting normal. We got a snow a few days ago and she hid in a little cave-like space under the snow after the pond froze over. She hasn't been eating or drinking anything that I know of. I put come corn and water out for her but she still won't eat or drink. When I go out to the pond she would usualy try to stay away from me such as going to the other side of the pond but now she barely moves. I do not have a coop for her but I did build a small shelter out of cement blocks, rocks, and dry grss for a roof and bedding. During the summer I fed her corn with pellets there but she never stays in it. I hope that this is normal and that she isn't sick. Any suggestions would be helpful. Thanks in advance.
