No. Heifers are female, bulls are male. Heifers cannot change their sex like some other creatures can. However, heifers that were born with a twin brother and shared the same placenta with her twin brother can develop bull-like characteristics. These are called Freemartins or Hermaphrodites. Hermaphrodites are 100% sterile, and a hermaphrodite heifer is a heifer that has both male and female sexual characteristics but can not fully become a bull like REAL bulls are.
This is the wrong question to ask, actually. You should be more concerned about the age that you should put a heifer in with a bull to be bred, not when should a heifer be taken away from a bull. See the related question below, but generally, a heifer should be at least 15 months of age to be bred and be able to grow a calf in her. Now to really answer your question, the bull should be removed after a couple months of being in with the heifer[s].
No. The bull should be separate from the heifer and her calf simply because it's less stress for her and enables her to mother up to her calf without having to be getting after the bull if he tries to interfere with her.
Don't do it if the bull's way too heavy for the heifer and you can't get semen from him sufficiently to AI her. Most herd bulls are mature beasts, but if he's a yearling or a small bull, then go right ahead, put her in with him.
"heifer" is a cow that has not borne a calf, or has borne only one calf. Cows are female and the male is therefore a bull.
No.
You could call it a heifer, or a twin heifer if the sibling is also a heifer, or a freemartin if the heifer's sib is a bull calf.
The masculine form of heifer is bull. All baby cows, prior to sexing are referred to as calves. A castrated bull is called a steer.
The male counterpart of a heifer would be a bullock or a young virgin bull.
No. What a heifer or any female eats as no effect on her reproductive cycling or her receptivity to the bull. A heifer that is bred is a heifer that is not nor will not come into heat for several months.
A calf is a heifer calf if it's female, a bull calf if it's male.
Like this:"The farmer had a prized heifer in the cattle shed.""The heifer was bred by the herd bull yesterday.""The cow gave birth to a heifer calf!""Those blasted heifers got out again!!"

Bull calf, heifer calf.
Put a calving-ease yearling bull in with her.
