Hello all! I have 5 chicks that are about a week old and all are doing pretty great! But I have noticed that my little Speckled Sussex has a crop that is constantly swollen. She doesn't seem to be in any distress and is eating and drinking fine. So I'm not sure if she's just pigging out all day every day and it's just always full, or there's a problem. My question is: Can I mix Poly-Vi-Sol with ACV in the waterer? I've been using the vitamin drops for a few days now for all the chicks, but wasn't sure if it'd be ok to mix the two together? Any other thoughts or advice? Thanks!
