We have one pet hen. She is having a sour crop. She has much gas. I can feel it and massage it and she basically burps. I can feel a thing in her crop. It feels like a small slimy piece of grape with tiny balls on it (like ball bearing, small though). It sinks to the bottom of her crop. I fed her some grit and I am wondering if they also attached to this small clump. I don't know who she could swallow something magnetic?? or maybe they just clump together. I have been treating her with coconut oil and GSE. And vomiting. I need to help this clump get out of the crop. A vet is not a financial option. I am afraid to do surgery. I know the exit of the crop is UP a bit. Is there a way to massage and push it through the opening to the proventriculus? Do you know where that is? Could it be between the beast bone V? *Is there anything that will stimulate the crop to push it out? Do you know if fighting any yeast etc will help her move her digestive system and pass the clump? Thank you! p.s. If I had to surgery do you know of a step-by-step instruction somewhere? My biggest concern is the closing of the wound. And the tools.
