It would all depend. The foal could have any color father. He could be black, and if one of more of his parents what chestnut, and the same thing with the mother, then the foal could be chestnut, but the most likely thing would be that the father is chestnut.
Most likely would be cremello, palomino, chestnut (sorrel) or another buckskin.
When you cover your mare on Howrse, the owner of the mare gets to keep the foal.
No. The male gets the money for cover, and the female gets the foal
Isabella or Isabelo is as light as it gets.
Isabella or Isabelo is as light as it gets.
A mare has an insticnt and will not I repeat will not become pregnant before the foal is weaned but that is why a stallion that the foal is not sired will try to kill the foal so he can sire another foal of his own.
It depends on what genes the foal gets. You didn't mention what color the horse was before it turned grey, so that makes this difficult to answer. Grey isn't a color gene all its own, its a color modifying gene. Grey horses start out a normal color, and then their coat grows lighter as they mature.If the grey horse is dominant for grey, the foal will most likely be born a color and change to grey as he ages. If the grey horse is not homozygous for grey, then the foal has a 50-50 chance of being grey.
You can use a goat to raise an orphan foal, at least partially. However, the goat may not produce enough milk as the foal grows and there is a difference in the amount of fat in the milk of goat and horse. Also, it gets tough for the foal to nurse from the tiny goat as it grows. You may prefer to milk out the goat and feed the foal by hand. I would suggest that you feed at least partially with a mare's milk supplement available from your feed store to make sure the foal gets the proper nutrition. Leave the goat in with the foal. Goats make lovely companions for horses and your foal needs a companion as much as milk.
The exact color of the foal will vary according to the exact genetic coding of both parents and without that information it can be almost impossible to tell you what color a foal may be.
The very short answer is, No. A palomino horse is no different than any other horse. A palomino gets the name from the color of its' coat - it is not a breed, not like Arab or Quarter-Horse. A palomino colored horse can be registered as Palomino, but it is still just a registration of color, not breed. Of course, any time you are dealing with any animal that has a typical adult weight of well over 1000+ pounds, some smaller animal and even humans will eventually get stepped on accidentally. But are they a threat or dangerous...no.
Most orphan foal milk products are designed for the foal to be weaned at 2 to 3 months of age (about the same amount of time a foal gets it's primary nutrition from mare's milk). While the foal can be fed milk supplements through the 6th month the amount needs to be reduced as solid feed intake increases to limit inflammation of the growth plates.
Newborn foals are thin on purpose. This allows them to pass through the birth canal much more easily than if they were plump and fat. The foal will gain weight as it nurses and gets a bit older.
