I have been nursing my chicken I have had about 7 weeks now. The past 2 weeks she has gone down hill and gone down hill and is skin and bones I have given her penicillin shots been force feeding her not getting it into her air ways. And as of yesterday she has been unable to stand. I have been emptying what is left over in her crop everyday it's very sour smelling each time. Now she's so weak she can't even hold her Wings up and laying to the side. She just started today gasping for air. And I hear fluid sound I feel like this is her final stage of dying and I am heart broken. But I needed to know is that a sign of fluid in lungs the way she is gasping? She is not alert and her comb and wattles are now deep purple have been for 3 days now. 2 weeks ago they were pail in color. I have read and looked up every possible sickness and issue and have not came to any conclusions. I have no history of her past until I found her. She has never once laid an egg. I'm just so sad and worried about this girl.
