All, it seems best to just go through the suggested questions (that are posted at the top of this Forum): What type of bird, age and weight > 1 NH Red Chicken Hen, approximately 1.5 years old, has lost weight and is lighter than other sister-hen. What is the behavior, exactly. > Her behavior has changed since the symptoms have gotten worse. Skittish, Irritated. Has scratched feathers from neck trying to itch ears. Tilting head and opening mouth (almost like a deep swallow) periodically. Shaking head periodically. How long has the bird been exhibiting symptoms? > 3-4 weeks Are other birds exhibiting the same symptoms? NO, not at this time. There is 1 other NH RED hen of the same age. There are 4 Rhode Island Reds (we got as chicks June 26th 2017). The 4 Rhode Island Reds are not fully integrated yet. They are in a separate living space inside the coop at night. They free-range in the day. Is there any bleeding, injury, broken bones or other sign of trauma. > Other than feathers have been scratched away around neck area (see attached pics)... no bleeding, injury, broken bones, no equilibrium problems, and no other signs of trauma. There is Dry, grayish, brownish discharge around both ears. (see pics) What happened, if anything that you know of, that may have caused the situation. > Nothing that I know of. I have been researching chicken ear infections and ear mites... the symptoms don't sound like a match for what I have seen. What has the bird been eating and drinking, if at all. > Pellet food has been from Tractor Supply: Purina Organic Layer Pellets, 35 lb. and periodic veggie scraps and treats like watermelon, cucumber, etc. We do let them have some Tractor Supply chicken scratch occasionally. Also, what ever the Hen finds on the ground when she free-ranges. Only been drinking water. Hen does seem to be eating and drinking well/properly. How does the poop look? Normal for the most part. Maybe on a little on the runny side. What has been the treatment you have administered so far? None so far. I want to make sure I know what I'm dealing with before using any medication or treatment. What is your intent as far as treatment? Treat the hen myself. If you have a picture of the wound or condition, please post it. All pics attached of Hen and her environment. Describe the housing/bedding in use. > Tractor Supply Co. Flake Premium Pine Shavings, Covers 8 cu. ft. I do change the coop bedding every 2-3 weeks and sometimes add fresh bedding in-between. When the coop is empty I spray straight white vinegar and let dry before adding new bedding material. Other > I checked for mites on new chickens and the Hen in question (around neck and vent area) and see NO signs of mites. I live in Southern New Hampshire. Thank you very much for you time and I hope to try to find an answer and treat soon. I will do my best to respond to any/all questions. By the way... her name is "Little Bitty" because she was smaller and feistier than the other chicks when we got her.
