Wow that is great that your barn is so bright! I just had electic put in my barn this past summer, tried a year without but this winter was so much nicer having lights!!!! Also had a ceiling fan put in which is great on those hot, humid Virginia summer days! When I planned my barn I had a window at each end and 2 on the back side with double dutch doors in the front but it still doesn't look as bright as yours does! Your girls look so happy and content in their stalls!! I can't wait to see their foals, I'm sure you are getting really excited!!You have many babies to look forward to, foals are just precious the first few days!!!!!!! I'll be watching, hope to see some little foals soon!!
