Monkeys come in a wide variety of colors, and the term "ginger" is not a recognized scientific classification for any specific type of monkey.
To answer your question about a baby monkey's weight, we need to know which species you're referring to. The weight of a baby monkey will vary greatly depending on the species.
For example:
* A baby Capuchin monkey might weigh around 100-150 grams at birth.
* A baby Mandrill could weigh up to 1 kg at birth.
* A baby Gorilla might weigh around 2 kg at birth.
If you can tell me which specific type of monkey you're interested in, I can give you a more accurate weight estimate!
