Found my hen on the floor of the coop instead of on the roost with the other hens last night. Brought her in the house where I have her in a pet carrier. Her breathing is labored - she stretches her neck up and opens her mouth 1/3 of an inch for every breath. And, I can't see her tongue! I've been giving her droppers of two mixtures: one is cold-pressed olive oil with liquid garlic and the other is epsom salts dissolved in water. She ate two bites of cooked, cooled organic brown rice this morning, but will not drink on her own. Any advice? I'd really like to save her, of course.
