they will kill her
take her out and put her in a box or other pen, maybe you can spare some room in your laundry room?

if she doesn't have bloody stools, follow the below, if she does, buy some corid and follow the directions on the bottle

In the box, put hay/shaving or something, (her feet will be buried a bit) then force a capsule of vitamin E down her throat. Poke a hole and squeeze the goo down her throat, you can gently open her beak with your finger nails and keep open with your pinky. Do that three times a day for two days, then down to once a day for another week. Fresh food and water but mix the food with whatever her fav is, because sounds like she is off food, you may need to hold pieces of red grape in front of her so she pecks at it, eating tiny morsels. Just enough to keep her alive. If you have the money, buy meal worms from the pet store, WAY better but pricey. Hand feed her the meal worms until she is back to foraging on her own.

keep me updated on symptoms, just in case it's something else entirely



Ok, if she isn't responding to this treatment but is drinking water on her own, put in Corrid, again pricey but she is

I'm guessing that you live in dry conditions which would cause the feet to be dry. So, yes, get some oil on her feet (I use a mixture of jojoba and tea tree) and definitely separate her from the rest of the flock. The other chickens know that she is not well. She is asking you to help her. Try to get her to eat some sprouts. They are good for all of your flock.
