You stop feeding them when they die.
About half the size of your hand.
Baby guinea pigs will usually fit right into the palm of your hand, and have quite large feet; adult guinea pigs are easily the size of a football.
stroke it and try feeding it carrots from your hand, let it learn to trust you. It'll take time but it does work.
If you are hand feeding it it's crop is probably a little too full.
Mice can not digest diary. Feeding a mouse cow milk can cause an imbalance in its digestive tract. If you need to hand feed a baby mouse, which is very hard to do, then you need to use milk replacement formula made for puppies.
guinea pigs are quite alert creatures so they do not learn to trust you very quickly, even if it trusts you it could take one wrong move to shatter it. my guinea pig and me get along fairly well but he is still causios if i make a sudden jump or somthing even though we've had him for over 1 year. my advice is to let him relax when he wants to and try some hand feeding , hand feeding guinea pigs shows them that you mean them no harm and just trying to be their friend, treat it like a human. hope I've helped.
There are a few things you can do, but guinea pigs are prey in the wild, so no mater how buddy-buddy you get with your guinea pig it will still run away when a hand goes to grab it, it's just a natural response. Try talking to the pig. Guinea pigs can get used to your voice, and will squeak with joy when they hear you. Also try hand feeding your pig. Get one of her/his favorite treats and feed it to your pig with it in your hand. Guinea pigs love food and would eat 24/7 if they didn't have to sleep, so food is a great way to your guinea's heart!

Because Wanda raised the fawn by hand, feeding it from a baby bottle, the animal retained its human imprint and was not afraid to eat grass in the back yard.
You put your hand under it's but and lay your other hand on it's back. The guinea pig should be leaning on you.
you don't have to stop hand feeding your lorikeet if you do though it just might make the lorikeet trust you more.
no, the oils from your skin will not harm your guinea pig.
place your hand flat
