In her flock my Mom has a banty hen, about three years old, that has become ill and is declining rapidly.She is half Silver Sebright and half Porcelain D'Uccle. This little hen normally weighs close to three pounds. Now though she is very underweight, and feels emaciated and very light when you pick her up. The first symptom we saw was that instead of flying up to her favorite perch in the top of the chicken coop roof, Mom found her huddled on the floor. That was when she discovered that she had lost so much weight. The hen had seemed to be doing fine until then, eating well and going out and scratching with the other birds, etc. Since the weather has been cold, Mom moved her into the house when she got sick. She seemed to perk up when she got warm, but now is going down hill again. She has a good appetite and is eating well, but seems to be starving anyway. She is eating a combination of fermented whole grains and commercial layer crumbles right now, she was on layer feed and some scratch before she got sick. She is getting weaker everyday, and now is staggering and having trouble standing. She does not have any diarrhea, no respiratory symptoms, and her crop seems normal. She is still singing her "hen song" and her eyes are bright. The only thing I can come up with is mabye worms, but there haven't been any signs of those in her poops either. I know this is vague, but does any of this ring a bell for anyone? I am at a loss personally, and we would really hate to lose this sweet little hen.
