I just heard a bunch of ruckus coming from the box the chicks are in and decided it was louder than usual so went to look. I found one of my pullets with its head twisted and in the waterer base. I quick grabbed it out and tried to checkit out. It spazzed as if having seizures and its head flopped. It kept opening its beak as if it was choking. I couldn't see anything in its throat. It spazzed some more and then died. I have no idea what happened. It was perfectly fine earlier, it was one of my bigger pullets and seemed completely normal. what could have happened? I don't think I am ready for this!
