Thanks everyone, I think she is so cute too.
I just got in from feeding her. this time she willingly took 50 cc's instead of the 40. The mare had no milk in the bag but the nipples were moist so the baby must have nursed it out, I see her sucking for about 25 seconds a couple of times between my feedings. I'm happy to say that I had to loosen the little blanket that I had put on her two days ago so she is growing.
The filly is starting to lay more now with her feet tucked under her instead of straight out and jerking so much, she is actually running around in the stall right now, it's good to see. She sure is cute, I think I need to think of a good name for her.
By the way, here in WI it is spitting snow with high winds, did someone say it was April?
