My 1 year old hen start gasping for air for the last couple days that ive noticed. This morning her comb was a little darker red and looking a little purple towards the back of it and her breathing seems a little worse. No nasal drainage or bubbles in her eyes so I'm not sure what to do. She was eating and drinking when I first separated her but I haven't seen her yet this morning im guessing because her breathing is worse. Any help or suggestions would be greatly appreciated!!!
