am I ontrack with my daughter's heifers?

[Jcran]

We lost my daughter's springing heifer to what appears to be "redwater" back in late June/early July, right after our fair. We bought two bucket calf heifers and a bull calf the following week. We just weaned them on Sept. 14th, at about 3 months old. We gave covexin8 to all three and wormed them tonight with ivomec+. We plan to disbud them when the 4H leader can come with her big disbudder (my goat one is just too small) and give them something called "bovi-shield" then. They are getting an 8-quart bucket of grain to share twice a day and cleaning it up at each feeding. They get pasture (dry and crappy right now) and free choice alfalfa.
The calves weighed in at:
Jersey Froggy 6/19/11: girth: 36 inches = 158 lbs
Jersey Sadie 6/3/11: girth: 41 inches= 224 lbs
Holstein/Jersey Bull calf late June: girth 40 inches=208 lbs

I am thinking this is in the right zone? Anything else I should be doing for them?

I have never heard of "redwater", what is it?

A clostridial bacteria I believe. I found out after the fact that one of the showmen at the fair lost cows to it...I let my daughter's heifer drink out of the communal trough at the fair. The vet said that even though she was vaccinated, in areas where it is bad, people give shots every 6 months instead of annually. It was a horrible thing.

I do not wean according to age but according to how much grain and hay they are eating . I also have extra milk now so my calves and kids tend to stay on milk longer . Watch for cocciida at weaning
