Update:
The foals had tummy aches from being out on green grass in their pasture which created a lot of gas and made them colic.
Filly #1 has pretty much gotten past it and is coming home today.
Filly #2 was much worse yesterday. She had a fever, an elevated white count, and was very bloated, so a decision had to be made about surgery. She had surgery last night and they found that she had flipped her colon and it was about to burst because of so much gas build-up. They un-flipped it, flushed her out and aspirated the gas in the colon. She is holding her own today, and is starting to nurse. She is not out of the woods yet but hopefully she will be home in a couple of days.
Thanks for your continued prayers.
