So far they seem to be doing OK. Thank goodness it's not cold weather! I covered the brooder with blankets, making sure obviously that they have gaps for air, put several (very tightly covered) bowls of hot water in there wrapped in towels, some extra towels for cuddling purposes, and one of those athletic heat wrap things wrapped in a towel as well. One weak one I've been keeping an eye on is pressed up against a bowl of hot water and I think I'll take that one out in a minute and keep her close to me for warmth, but the others don't distressed so far. I'll keep close watch and switch out hot water as needed. Any other suggestions? I didn't post in emergency because they seem OK so far, so I hope this was an OK place to post this. This is one of the many times I'm very thankful to be able to stay at home with my very young daughter!!!
