What kind of sickness???

[ChickasaurusRex]

I've had 3 young pullets die before they could lay an egg. All of the same symptoms: droopy eyes and wings, unable to stand/walk, small sudden bursts of kicking/flapping wings and what looks like gasping for breath. Also can a chicken die from an abscess? Recently my hen passed away after getting a huge lump on her cheek. I thought the pullets died of Cocci so I treated the rest of the flock for it.... What's going on?! I really don't want anymore of my babies to die in my arms

Look up Marek's and see if those symptoms match. It spreads rapidly in a flock with no cure.
It wasn't coccidiosis.

Really?? Oh dear I hope it's not Marek's...They were all vaccinated
