is there any reason my pullet would've died?

Corid won’t hurt them and because of the amount of blood and them all being puffed up (that is a big red flag regardless if weather) I would treat them as soon as you get the corid.

I picked up the corid at TSC, I have a appointment so I'll treat them when I get home
