Whew! Four bum calves is wearing me out. Luckily with calves, you can feed them only 2-3 times a day and they do fine. Two are twins (one each from two separate sets), one was rejected for one reason or another, with cows you rarely figure out why, and the third was never claimed by a cow (so who knows what happened there).
Hopefully, we have a home lined up for two of them; a local youth raises bum calves then buys books for the state youth home with his profits after selling the calves. Hopefully that will work out, so I can be down to just two calves, sooner rather than later. Shayne said we should get a dairy cow to raise the bum calves, but I don't want to take care of one; and what if you get one that doesn't want to raise someone else's calves. [We don't often have bum calves to worry about, but it seems to go in streaks, few years in a row with one or two, then a few years in a row with none.]
