I have a black copper marans hen with what I believe is a respiratory issue. She is about a year old although I did not raise her as a chick but got her from a breeder and was told she is a year. I have had her a couple weeks. She has been in a pen with 2 other hens I bought her with and a BCM rooster that was also in quarantine. The other 3 birds are having no issues (so far ) yesterday morning I came out to find her acting sickly sounding a little wheezy. I pulled her from the pen and brought her inside and is isolated in my shower right now. Here are the symptoms. Slight wheezy sound Milky watery poo that has now started really sticking to her down although her vent is clear watery eyes and nostrils Lack of appetite or thirst. From what I can tell she has not eaten and drank very very little. I have offered her scrambled eggs, Greek plain yogurt mixed with chick crumble, grow gel, crumble, and bread. Nothing has tempted her that I have tried. I have tetroxy HCA-280 (oxytetracycline HCI) Antibiotic. It is a soluble powder and if I cant get her to drink not sure how I am going to get it into her. I am afraid to force her to drink and end up aspirating her airway or something. I also have Vitamins & Electrolytes that I have mixed with some water that is available to her but she hasn't drank any. I also have Sulmet (sulfamethazine sodium) drinking water solution, 12.5% Outside of these items I wouldn't have anything else available till tomorrow so not sure if any of this will help her. Any suggestions or ideas would be greatly appreciated. I am tempted to bath her to get her down clean from the poop but am afraid of making her sicker so at this point besides isolation and providing food and water I have not really treated her for anything.
