I’m having a hard time with these chickens, everything I‘ve raised up until now has been easy compared to these meat birds. I have 39, they turned 2 weeks old today. They all look fine, have been active, are eating, poop is fine, no blood. I have kept their brooder super clean, offered clean water and everyone is eating fine. Bedding is pine shavings, I clean it out daily. Today they all started sneezing and sound raspy/rattley when breathing, no discharge at all from what I see. This came on quickly. I’ve been reading and reading, it looks like I need antibiotics .. but it’s not sold without a prescription? I guess I need to contact our vet in the morning and see if she can help? Thoughts or advice is welcome, I raised lots of layers and never had these problems.
