Just a few more to go. We're slowly getting them back to being timed right.

Very cool. What got them out of whack in the first place?

Weak testing bulls for one, replaced the 2 bulls, also the cows were in general poor health, despite regular feeding, free choice minerals etc, our veterinarian recommended we start using Ivomec Plus, and a 6 way clostridial vaccine, they can prevent alot more parasites and diseases that can cause reproductive issues, abortions etc... which we were starting to have issues with and birth times were getting spread out due to sporadic breeding.
We've had no more issues.

Glad to hear everything's getting better.
