I have a 2 1/2 year old BO who is extremely weak. Her weight has gone from 6.8 lbs to 2.1 lbs. She has been checked by a vet; all tests came back normal. X-rays show nothing irregular. She has no parasites inside or out. According to the vet, she is healthy. I had what appears to be the same thing happen last year, that hen finally recovered. This is Sadie, a very sweet girl. She is eating and drinking, her droppings are normal. I brought her inside last week because she was so weak and gave her Nurti Drench for four days then put her with the flock. She seemed to be a bit better. I had read that more than four days on Nutri Drench would give her diarrhea. She sure doesn't need that. I just checked on her, she was trying to drink but is so weak she couldn't stand long enough to drink. I am going to bring her back inside. My question is, how long can I give her Nutri Drench? Is there anything else I can try giving her that might help? She is going to die if I can't come up with something. Also, I am wondering if I should put grit in the crate with her if she is inside very long because she is eating ok. Thanks.
