I am really disappointed. I seem to have hit a rough streak :/ For some reason, my chicks are just dropping dead on me. I lost 3 of my 5 blrw in the past 24 hours, about 4 turkey poults and a few other random chicks

I've been losing silkie feathered lavender ameraucana chicks here and there but they're frail to begin with so I wasn't thinking there was a problem until now. I've never had issues like this in the past and it's so upsetting. Brooder temps are not too high, fresh food and water every day, they're on towels so bedding isn't an issue. They aren't showing any signs of distress until right before they die. I've started corid in the water, hopefully it helps. I just don't know what to make of it :/ I REALLY didn't want to lose any of the blrw babies
