Selection for calves that are growthier and have larger weaning weights tends to correlate birth weights. Breeds that are known to have such calves, like Charolais and Simmentals, will often have big calves. Also, feed that is high in nutritional value given to cows close to calving will also result in large calves. Large calves also tend to come about during during winter than in the summer. Thus it's all down to genetics and breed, as well as feed and environment that determines size of calves when they're born.

When do a baby an elephant start walking?
Almost immediately after they are born. Elephant calves can walk minutes after they are born. They are born in the dangerous jungles where, if they are in the same place for long, they can easily fall prey to large predators like Lions. That is why, nature has made them able to walk so soon
Do older bulls sire bigger calves?
No. Just because a bull is old doesn't mean he's going to sire larger, heavier calves. An old bull can range from a small mini Angus bull, to a big Charolais bull. Calf size is depending on the genes for birth weight in both the dam and the sire. If the sire has a large birthweight himself and the cow has the genes for siring large calves, then the calf will come out large. Size of the calves also depends on what you feed the cows in their last stage of pregnancy. High concentrate feeds fed to a cow in her last trimester can make for quite a large calf, no matter what condition the cow is in. Young unproven bulls are even known to throw large calves, especially if they have the EPDs for large calves from their dam and sire, or have a high birthweight. The chance of an unproven bull to throw large calves is much higher than with a proven bull that has already proven that he can throw small or large calves.
Why are whale calves born tail first?
it probably would take a while for them to "be born", so they would probably suffocate with their heads in the water so long

What do you call more then one baby cow?
If it is a group of calves born from different mothers than you call them a herd of calves or a group of calves. If it is two calves born at the same time from the same mother than they are twins, just the same as human offspring would be called.
