We had two of those surprises last spring
my grandpa had nine of those this spring. they were not replacements, although a couple of them are replacement quality. they were born around last spring, weaned in november, and what do you know, heifers start calving in march. a few were older than 16 mo. and im sure a few of those were younger. my grandpa always hold his weaned calves from fall until april/may. then sells.
first heifer was absolutely nuts. and had take her to vet to get the calf pulled. calf is doing great, it has outgrown many of the other calves that were born about the same time it was born.
we thought that was the only one. i knew there was one more to get it but she was one of the last ones. i found one heifer by accident in the pasture tryin to have it. pulled it and calf died about a week later. heifer sold with the rest of the calf crop. ended up losing three of the nine. all had to have assisted calving, one came out dead, the other had a limp and died the next day, it was about two weeks or so.
a total of 6 of the 9 had to be assisted. fixin that problem this year though, since it is pretty much a year round calving season we weaned all calves that weighed over 450 in late may and the next weaning will take place prob. in sept. that was one h*ll of mess.
sorry bout the rambling but that was the first time i ever had to deal with something like this
