I have a 17 wk old EE Hen. Not laying eggs yet. She free ranges during the day and is in the coop at night. The bedding is soft wood chips She eats complete layers feed and lots of grasshoppers Today I noticed her making strange "honking" sounds when she breathes. Also she is sneezing and what sounds like coughing. She is alert, no lathargy. No nasal discharge. Clear and bright eyes. She Is eating and drinking well. She was in with a small flock of 8, including her. I seperated her and have her in the house in a cage in a dark and quiet room. It has been raining all day today and it's a little chilly. I had to run some errands and was gone for a couple of hours. when I came back she seemed better. She isn't "honking" while she's breathing. I haven't given her any medication yet. I have some antibiotics that you add to drinking water, should I medicate her with that? Should I medicate the whole flock? Can I eat the eggs of one of my laying hens if I do medicate them? EDIT: She's outside with the rest of the flock now. She hasn't made any loud noises or sneezed since after I brought her in the house. Is it possible she had a reaction to the sudden change of weather? It was borderline hot yesterday and today it is cold and wet.
