I have a 4 week old bottle calf half holstein/jersey or all holstein. He has pink eye looked on here and been doing the 2cc in the eye. Plus 5cc shot every other day 4 times. Now when I get ahold of him his hair is falling out there is none on his butt and its coming off around his nose. I am feeding 2 qts 2x day of medicated milk replacer. I have also put some fly spray on him cuz the flys are terriable. What could be the problem? We just put the calves outside monday they where on the barn. I thought the breeze would keep them cool and the flys down a little.
