Thank you so much for your reply! I think I caught it early - I checked her head carefully - there's no drainage from eyes or nose and
she is eating and drinking. Her poop is normal. After I posted, I tried several times to videotape her so I could show folks who might be able to tell me what it is. I tried for over 20 min. she never coughed or sneezed once. I gave her a pile of slops (leftovers that are chicken-safe) - she dove into it - was shaking her head a lot and wiping her beak but I think that's from her whole head touching the food. I decided to give her the Safeguard. I have an oral syringe that is great for shooting into their mouths. I read in another post how one owner gave each of their average-size chickens 1/2ml right down the throat. I weighed my chicken - 4 1/2 lbs - so I gave her the same dosage to start. I held her, put the syringe in the corner of her mouth shot it in - and she sneezed it all right back in my face! Lol! Still holding her, I drew another shot - this time, 1 ml (to allow for waste) and she swallowed most of it. After reading your post - I see she probably got a good dose for her weight today. I put her back in my quiet family room when, all of a sudden, she heard the rooster right outside the door (he knew she was in there). She ran to the door, I let her go out as the sun was shining and it was almost 50 degrees today - she looked fine. Later I went out to check on her - she's acting like her old self. I am wondering - do you think I should I keep her inside tonight? Her nesting box is detacheable - I can bring it in for the night. We have a woodstove in our family room - it's about 65 degrees. The coop will probably be about 35 degrees tonight. This morning she ran into the house and sat in front of our little space heater for about 5 min. after spending the night in a 25 degree coop. I have a heat lamp in the coop which I only use when the temp goes below 25. I turned it off 2 days ago - she has not laid an egg in 24 hours - but I attribute that to a rest from the bright red heat lamp. I will continue the safeguard - 1 1/4 ml once a day for 5 days. If you can think of anything else, please let me know. I give layer feed along with an afternoon snack of slops and leftovers - mostly made up of greens and fruit. I can increase her protein, no problem.
