18 weeks or when they lay their first egg. Any sooner can cause kidney problems with the high calcium content.
they should be feeding from their mother if they are newborns :) but after about a month you should start to feed then soft and broken up food in small amounts x
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.
Continue feeding with Layer mash or whatever you have been feeding them if they are otherwise healthy. Molt is natural and will take up to three months.
Mode of feeding is how you would be fed should you not be able to feed yourself. Feeding tube, intravenous, etc.
Chicks can be slowly weaned off chick crumble at about 6 weeks. Start by adding a small amount of chick grower each day until you no longer need the smaller size feed. Layer complete or laying mash can be started at about 16 weeks.
If the mother was feeding it in the first place, then it should keep on feeding it =)
by always feeding him and spanking him
You can start feeding a baby solids at 6 months of age.
once their "food sacs" are gone you should probably start feeding them one or 2 day later

You should train him first, then feed him. It makes him work for the food.
When in doubt, force-feeding is usually the right thing to do
