Lethargic and not eating

[ChickNanny13]

I have the same thing going on. I've lost two chickens in the past two weeks and this morning another one is exhibiting the same lethargy. That's how it started before the other two died. Of course it's Saturday and I can't find a vet that does chickens without taking her to the emergency for a beginning cost of $115. I want to stabilize her for at least the weekend and try to find a farm vet Monday.
I'm not trying to scare you. But I did a necropsy on the last one that died two days ago and all she had was wet feed in her crop. No smell no grass nothing. For the life of me checked her everywhere and I couldn't find anything.
I'll isolate her in a cage and set her up. I have some nice mealworms to feed her. We'll see what happens. But if she dies over the weekend I will feel absolutely horrible.
