Just returned home from a week long vacation and had my father-in-law taking care of my 7 mixed breed 5 week old chicks. He was supposed to be feeding and watering them, but I arrived home today to find the feeder empty and the water bone dry. I know my daughter was home 5 days ago and filled everything (1 gallon waterer with a base, not nipples), but beyond that, I've no idea how long they've been without water. Most are pretty lively, but a couple of the chicks are more lethargic and are holding tails down. All chicks ran straight to the feeder when I filled it, and all chicks have also been drinking. Should I intervene or see where time takes them? I have electrolytes, yogurt, Corid, and multivitamin. Suggestions?
