Yes. Heifers can be eaten as well.
Usually it is better to butcher a beef steer but heifers are okay.
The term butchering can mean cutting and preparing meat. Butchering can also mean doing something very poorly or incorrectly as in butchering the English language.
A yearling bull, which is best used on heifers, can breed from 10 to 20 heifers in a breeding season.
Since yearling bulls are the best to use on heifers, and one yearling bull will breed from 15 to 20 heifers, you should have 4 bulls for your herd of 70 heifers.
Angus cattle are ready for butchering between the ages of 14 to 24 months of age. Be sure, though, that they already have good weight and body condition if you plan on butchering them. They won't offer too much meat if they're too fat or too thin.
When the heifers are at least 14 months old, you can put yearling bulls (15-20 heifers per bull for yearlings) in with them. Don't put your big mature bulls in with your heifers as this could cause problems later on.
Your heifers weight should be 60% of the cow herd's. But, they should also be around 15 months of age, though a couple months plus or minus isn't going to hurt either.
Heifers.
A yearling. Bulls are yearling bulls, heifers yearling heifers (or just heifers). Steers are often just called steers, sometimes yearling steers if you want to be more precise.

Yes. It's not uncommon to background or stocker heifers for beef like what is done for beef steers.
