I feel you! I just had twins born last Thursday and am worried for them too. Each day it has been upper 90's. Earlier this summer I lost a baby to what I believe to be heat stroke, so I am more cautious now about the heat. It sounds like you are taking some good steps in the right direction. I put a fan in my barn too, but with the high daytime temps, it's almost like a heater blowing on them. Most of the time, the babies get behind something and not in front of the fan until it gets late in the evening when temps cool down. They seem to prefer the bare dirt floor to any bedding material I put down. My kids also prefer to find a nice shady spot outside the barn as well. You might consider freezing a gallon jug of water and putting in front of the fan or in the pen with your goats. Maybe put some ice in their water if it's hot to cool it down and encourage them to drink. Electrolytes in their water would be a good idea too. It's important to keep them from dehydrating. Also, keep them (newborns) out of the direct sun, especially if they are a dark solid color. My little kid I lost got separated in a small pasture from mom and sibling when she was only a day old. It didn't take long for her to overheat in the direct sun as temps were in the upper 90's. I try not to have babies in the heat of the summer as well, but sometimes things happen! Best wishes and come on October!
