That might be a good thing. But the only other advice I have is you have the infamous "lethargic chicken" I have never seen a great answer to this. Mostly just supportive care. The drench and poly were a good thing. All I can offer as advice is to throw anything you can think of at her. Doing anything is better than doing nothing. I have had this a few times and tried anti-biotics, electrolights & vitamins, any treat I thought she might eat. keeping her inside warm and in a dim quiet room. It has been partially successful.
Wish you good luck
