Welcome neighbor and I'm so, so sorry to hear about your girlies. I agree with what's been said thus far. Keep them clean, warm and dry. Make sure food and water are close and some electrolytes or yogurt (something to tempt them) couldn't hurt a bit. You're battling shock for the most part and birds don't deal with shock very well. Let us know how it goes and I've got a few extra girlies that I've been thinking about moving out to make room for the new hatchlings if you think you want to replace the ones you lost.
