Heifer heats easier to detect than cow heats
Still no best time to watch for standing activity, just a longer window.

Getting heifers bred can be difficult, especially if you don’t have facilities that allow you to easily lock them up for breeding.
How to synchronize heifer heats with a CIDR
Use this new reproductive tool to tighten your heifer program's breeding window.
Heifers less sensitive to breeding time
To achieve the best conception rate, the ideal time to inseminate a cow is four to 14 hours after the onset of estrus.
