I talked with the vet last night about the necropsy report on Holly. IT WAS NOT MAREK'S!! That's the good news. Results showed visceral renal gout and uric acid (this is what was causing their paralysis)

I got these 2 when they were 3 months old and so thought it was OK to get them started on the layer. I had no idea this would happen.
Leadwolf I have no idea how old your birds are, but could this be a possible problem for you, too?
I hope this helps out any others that mat be experiencing this problem. Thanks.
