Lethargic Chicken and Droopy Comb
A floppy comb may not have any significance at all especially in some large combed breeds such as white leghorns. In some cases, dehydration might play a part. She seems to have her feet crossed--is that just something that happened, or just a fluke? Can you put some vitamins and electrolytes in her water, and make sure that she is drinking well? Some brands such as Rooster Booster Vitamins With Lactobacillus has probiotics, and Probios is a brand of probiotics that can be added to water. Adult hens may get messy vents from excessive feathers or diarrhea. I would trim feathers, and work on finding the cause of her diarrhea or constipation. Placing her in a crate over night would allow you to see what she is eating, drinking, and get a look at her droppings. Worming might be a good thing to do.
