About a week and a 1/2 ago I noticed my hen wasn't eating as much and she was puffing up. I figured it was because it's colder outside. About 4 days ago she was REALLY sick. Dehydrated, loss of appetite, comb fell to one side of face and is now pink and not red, SUPER skinny! I posted on here and someone said she probably has worms. I got her the Safe-Guard Liquid Goat wormer (what they had suggested) and gave her 2 1/2 ml yesterday. She is still no better! She's so bad sometimes she'll collapse. Does anyone have any idea whats wrong with her? All my other birds are healthy. I'm clueless!
