So my chicks are a little over one week old. I have two in the brooder right now and so far they have been great. Seem to be acting completely normal. Today I was holding our little RIR and she suddenly let out a huge long clear mucusy drool from her beak. Almost as if she had spit up, but it was clear. There was quite a bit of it though. I put her back in the brooder and she went back to eating/sleeping. Should I be worried? I've never had this happen before.
