Guppy Breeding - a few questions?

If you know when your fish goes into labor or it looks like put her in the 5 gallon and when she has the guppies get her out ASAP she will eat them and you can feed the guppies the flakes and no don't put any gravel in there with them.The signs that i figured out when there in labor is is that she hides and she swims really fast goes to each corner of the tank go up and down the tank and stuff like that which is what my Oranda Goldfish is doing but I don't know if shes dying or pregnant cause iv only had guppies and i think shes dying but still think she pregnant.
