Juvenile bird dying

[GBandB]

I have had two birds die....they can not hold up their heads, tremble, seem to breath hard, and eventually start to seize. They can not get up, heads down, wings out...2 dead, and another doing the same...none of these birds have been together...all are juvenile silkies.

Please help if anyone recognizes these symptoms....

Tried syringe feeding water, water with electrolytes, sugar water....no idea what is going on...nothing helps.

Unfortunately there is too little information (for me at least) to make a guess. The only thing that is even half ways helpful is the seizures and that makes me think about Range Paralyses aka Mareks Disease. However that may be wrong as well.

Good morning
I have been doing birds for awhile but this is got me stumped. About 3 weeks ago I had a hen about 9 months, she stopped eating, lost weight and was extremely weak. I assumed that she was dying. I separated her. She still has not passed on- hardly eating. A week later a rooster same age did the same thing, I isolated him, he is still alive. 2 days ago , 1 more roosters stopped eating and became very weak. They dies in 2 days.
I am not seeing any watery eyes, hard to tell with poop but when the are isolated there is no poop.
I am concerned about eating the eggs. And what is going on!!
You might not be able to tell me definitely but ideas???
