If you accidentally disturb a mother with young do not handle the babies as she will abandon or kill them if they smell of humans.  Replace their cover gently and carefully with a stick and keep their whereabouts a treasured secret between you and a thankful mum.
 

If you do find an abandoned baby or orphan squeaking for help he needs protection from flies, a feed mix of ⅔ goats milk and ⅓ goat colostrum, from a goat farm or breeder.  If you cannot get to a goat farm then use Espilac, which is a puppy weaning formula and can be purchased from Spike's World.  Drip 1 to 2 ml. slowly from a syringe at 2 hourly intervals and stimulation to urinate after each feed.  The mother would do this by licking the baby's genitals.  You can do it with a damp tissue or cotton bud.
 

constant warmth is essential for his survival.
