I have a 2 1/2 year old hen that is exhibiting strange symptoms. About 2 weeks ago, I was finding her sitting off by herself, sometimes sleeping or just standing in the corner. She has not been eating much over the past few weeks and many times her crop would be quite empty before roosting. She is going thru a molt and is losing a lot of feathers quickly, so I attributed her lack of appetite to molting. Then sometime last week, I noticed that when ever she leaned her head down, liquid would come out of her beak. At first I thought maybe she had just drank a lot of water and possibly it was just coming back up. But I saw this again later that day and she has never done this before. So I felt her crop and it had very little if anything in it. But I picked her up and leaned her forward for a vomiting, not thinking much would come out of an empty crop, but it did. It just kept coming, like it was coming from further on down from the crop. Ok...so a day or so later, and still she is leaking fluid from her beak, I got a hold of her to see if anything would come out her beak and the fluid is starting to smell sour. Just like a sour crop would smell, but her crop is empty. The liquid is frothy and sort of yellow. So I started using vaginal cream on her twice a day and it seems to have tamed down the smell and the liquid coming up and out her beak. But she is still not right. If I stop the vaginal cream, all this starts all over again. She is eating a bit better since starting the vaginal cream. She is not suffering from a slow crop, as when she does eat, it moves thru her quick enough. Her crop is completely empty each morning. Her poop is nice and solid, dry with a nice white cap on it. She is drinking well, and eating, although not as much as she usually does. I keep all my birds wormed and on a good diet. Her comb is not pale and she acts fairly normal, although a more tired than she usually is. What would cause these symptoms...a bacterial infection somewhere in the GI tract? A yeast infection somewhere further down from the crop? She is molting...could she have eaten a bunch of feathers and she has a feather ball in her gut somewhere? Thanks!
