Not sure about all of this...

We’ve lost 3 chicks to the brooder. They go 24 hours without shitting then it all comes out at once. We’ve had a chick die with poop clogging both ends. Then another chick had poop clogging the vent and the next day the beak was caked in poop. I’ve taken them to the vet and I’ve been giving them probiotics and nothing has changed. I’m about to lose another one. I’m about to give up. I can’t take these little birds dying anymore. I’m so sick with worry. I’ve done what I can and it doesn’t work. I’ve had 3 chick deaths in 2 weeks. I’m about to pull the plug on the whole thing. I can’t take these little birds dying when I know they don’t have to. I’m out of my element. I know I’m not doing anything wrong. I’m out of my element. I can’t take this anymore. I’m so sick.<br><br>Not sure what to do anymore.
