My chicken is not doing very well. She has some poop caked on her butt. She hasnt been eating. I put her in some warm water and washed her up. She can't really walk, her belly is swollen, and when I tried to check for a bound egg, White liquid came out her vent. I cant afford to take her to a vet, Any ideas what might be wrong and is there any thing I might can do to help her?
