I rescued a flock of chickens 2 weeks ago, and all were in pretty poor shape. I already lost one bird to possibly a combo of sour crop and malnutrition, but I'm not certain. I have one hen inside now and I believe she has sour crop as well. She was treated for worms on the 9th with the safe guard wormer. She came to me VERY thin, but was eating although her wattles are droopy and not nice and red. I pulled her out of the coop on Saturday because she was looking even worse and the heat has been brutal. She was eating. Last night I made her a mash of yogurt, honey, crumbles, applesauce, and electrolytes that she picked at a bit, but not a ton. This morning she still had a squishy crop even though she had only water access all night. I gave her the mash mix in the morning and she hardly ate it. She has not pooped since yesterday which was watery. I read and read today and decided to try the red wine. I gave her 3ml at 7pm and it is nearly midnight now with no results. I have taken the food and water out of the crate. I had put acv in her water last night. From what I understand I should give her the water in the morning, as that will be 12 hours without it. At what point should I give her yogurt and egg, and how much do I give her? I am not comfortable trying to make her vomit, and I don't know that it's needed as I don't feel like her crop is over full with anything. As far as smell, she stinks, but I don't know if it's her mouth, or the fact that she's been just sitting around for days and has been sitting in poop, or whatever else happens to be under her. Am I missing something? Could it be more than sour crop? These poor birds were being given half layer feed and half corn, and I suspect the layer feed had gone moldy. I really don't want to loose another bird.
