Henny Penny is a tad over five years old. I hatched her as a tiny chick and she has been healthy and active for years until a couple weeks ago. I noticed that she has been panting or gasping for air. Her poop is pasty. I am pretty sure that she does not have a respiratory disease but I am a little suspicious of congestive heart failure and hope to be wrong. When I brought her inside, she seemed to do well. She was eating and drinking and even the gasping for air with her beak open seemed to diminish. I allowed her to go back with her group and it lasted only an hour, must have been too much for her and she was gasping again. I am just keeping her inside and keeping her in a dry warm climate in the house. She has a large cage that she seems to do well in and I also bring her in a small cage into the living room to be around us and not be lonely. I do bring in her other serama sister for a visit. I am sure she does not have anything that is catching. She gets a tad upset when I wash her bummy area with warm water to get the sticky poop off, but, she is getting used to it and realizes that I am giving her a service. She is eating pretty good and drinking water. I just don't know why she would be gasping for air unless it is her time to go maybe and she is having congestive heart failure. I had a large Americauna that had this and I kept her alive for two months which I hear is a record. This little hen though, does not seem to have a lot of water in her lungs. I have not allowed her to stay outside long enough in the damp and cold for her lungs to fill. All I can do right now is if she is on her way out, provide a warm dry place which is comfortable. I don't like the idea of putting her outside to die in the cold.
