So one of hens was making a lot of noise the other night so I went and got her. Turns out she had sour crop. I massaged her crop whilst holder her upside down and a large amount of vomit was released. I put her back in the nesting box and went to sleep, and because my room is next to the chicken coop, I could hear he scrawking and bumping her head all night. Next morning she had no appetite, wasnt drinking and not moving much either. So today I went out to the shops and bought some live yogurt, its called yakult and started squirting that down her throat as best I could. Right now shes inside because its fairly hot outside and her eyes are red. I am thinking she has had no sleep because of the sour crop. She has weird neck movements as well. I don't have access to anti-biotics for chickens because the vet is too expensive, but I've tried the yakult and feeding her scrambled eggs. She is drinking if you put her beak in a bowl of water. I don't want to leave her for too long because with the last 2 hens that have died, they showed the same symptoms, except for the sour crop and neck movements. Should I let her sleep, keep feeding her yogurt and water? I AM DESPERATE FOR ANSWERS!
