Nearly 2 year old SLW hen is lethargic--huddled on her own today. She isn't moving around much but does pick up her feet and peck at her own toenails (from the bottom). Her comb and wattles have been pale, she's just about regrown from a hard molt and hasn't been laying for a couple of months, but today her comb and wattles are looking jaundiced, kind of a pale orange color. She's a little dull in the eye too. She was wormed with fenbendazole and her treatment for that ended four days ago. (all the girls were wormed because I saw roundworms in one hen's droppings). She has been wormed before with this same safeguard once about a year ago and had no ill effects. Chickens eat organic layer pellets and organic cracked corn (as a treat) plus fresh veggies as treats. They use pine shavings for bedding and free range in our fenced yard during the day--not many things for chickens to eat there right now except some bugs and lawn. Water includes electrolytes and acv. No signs of mites or other pests. Vent looks good. No sores anywhere on her body. Her crop was in normal condition today although it was obvious that she had eaten very little except the corn I was feeding when I noticed her problem. Not sure if she was drinking. Her feet look totally normal, but she definately is acting like something about them is bothering her, both feet, btw. I brought her inside and she ate a whole egg scrambled with a little water in it. She wouldn't take any water, and only had two little pecks of layer pellets. She pooped twice since I brought her in. The liquid part of her poop is kindof Green. but the darker part of the poop looked pretty normal although it was a small amount and looser than I like. Anyone have any idea? I hope it is just a reaction to the wormer. My other hens are all acting very normally. I've looked at about a million posts, but haven't really seen those two primary symptoms. Tried googling too..."chicken pecking own feet" and "jaundiced chicken" but didn't find much except a few strange recipes and the idea for a really cool name for a punk band. ("Have you heard Jaundiced Chicken? They will blow your mind!") Thanks!
