I lost one of my older hens a few weeks ago. We attributed it to old age—she just started slowing down, lost color in her comb, lost interest in food and then stopped roosting until she passed in the night. Well now I have another one showing similar signs, and I don’t think she’s as old as my other hen was (though we don’t know for sure, we got her from another family and guess she’s maybe 4 years). She started kind of hanging out on her own about a week or so ago but honestly didn’t look sick—we decided to keep an eye on her and watch for other signs. We’re in GA and have had this crazy cold snap, low 20s and teens at night and she’s taken a turn for the worse. I brought her into our garage where it’s warmer and now she’s refusing water and food, little to no reaction when I handle her and just looks half asleep. I’m afraid it’s too late for her, but I’m wondering if we could be dealing with a pest issue. We’ve had no signs of respiratory issues or anything obvious. I’ve not noticed anything weird about my chickens’ droppings, no bumblefoot or injuries, can’t find mites or anything, but the pale comb and lethargy has me wondering. I’ve got yet another hen (between 1-2 years) who’s now got a pale comb, but she had a rough molt. I guess my question is: would it be worth it to try and de-worm them? I’ve got a goat wormer (safe guard I think), but I don’t want to stress them as it’s already so brutal with this weather. Here is a pic of my Jemima—you can kind of see a dropping, it’s white and runny. Side note: I haven’t checked for egg binding, don’t want to stress her out and would rather leave her in peace at this point. Besides she hasn’t laid an egg in close to a year.
