Tonight i noticed one of my icelandic hens was making a strange cawing noise.She was also opening and closing her mouth and had a sort of gurgling noise. I looked down her throat and it didn't look red or anything and i brought her to the water and she drank. She was acting pretty much normal trying to get away from me and doesn't feel like she has lost weight or anything. The hen is a year old icelandic. Any info would help.
