I am only asking because I just read a board saying a couple of their 3 week olds died. It kind of worried me. I thought after a couple weeks they'd be a little hardier... (mine will be 2 weeks tomorrow) I had them on electrolytes in their water until yesterday. Do I need to buy more? I also just moved them into a new, bigger brooder tonight. Will that stress them?? What do I need to do to keep them safe and healthy?? Thank you!
