Yeah, here's me suggesting Marek's to any other members ever again...
Nonononono, it DID match up really good, that was good reaserch on your part!!! I thought for sure it was mareks for a bit untill her symptoms changed!!
In your first post you said it was not egg binding, so I gotta ask, did you check for an egg? If this ever happens again, with some hens you can tell if they have an egg by gently palpating them. The fatter hens are harder to check that way, so with them I put on a glove, water based lube and very gently insert my finger into their vent. The treatment I use for this is a warm, steamy bathroom, oral fluids and calcium gluconate at 0.2ml per pound orally.
