This is the second calf I have had who became very sick, fever & resporitory type, doesn't respond well to antibiotics, as time goes on one ear droops down and they hold their head crooked. One of them died and the other one hasn't made up his mind yet. It sounds like an ear infection but since it is in two calves I wonder. They have had all shots and been wormed and poured. As usual you think you have covered all the bases but it doesn't seem to be enough.
