Looks good! I bet it'll be even nicer full. I would try what others have suggested, milk the full size. Helps to get the milk flowing in the teat and if the udder gets hard the kids will have too hard a time trying to work milk out of it.
yah milk the right side till it gets more soft and the boys will start to nurse off it as well. This will keep it from being lopsided perminantly. If you wait to long then it could cause perminant damage to her udder
