Any time of the year: Winter, Spring, Summer or Fall. Most commonly calving occurs in mid-winter to early spring, or for most grass-fed cow-calf operations, mid-spring to early summer. It's not uncommon to have producers calving in the fall, either, but this tends to be more common in areas were cold winters and snow is not as much of a problem as it is in the Northern States like Montana and North Dakota, and the Canadian provinces.

Calves don't ovulate. Heifers do. Heifers start to ovulate by the time they reach 10 to 15 months of age.

How do you start feeding weaning calves?

It depends on what purpose you have for these calves, and what you wish to feed them.  But really, you just start feeding them, start training them to eat whatever you set out for them, and let their curiosity get the best of them and get them interested in eating what you've set out for them to start eating. But, it's best to feed them what you have been feeding them prior to weaning, and continue feeding them this, slowly switching over to what you are intending to feed them in the first place.
