Now that you have the Mercenary DigiEgg, the DATA chips, and the courage, it's time to try to hatch your digimon! ......yes, I said 'try'; it almost never works, but don't be too discouraged! you can succeed with a lot of effort, and patience! This step is called 'Feeding DATA' because in this step you put your DigiEgg into the incubator and 'feed' it the data from the DATA chips. All you have to do in open the incubator, right click your mercenary egg, and press the middle button on the lower part of the incubator window. This will attempt to feed the data to the DigiEgg; but will fail at doing so most of the time. Now, sadly, it gets much worse. Not only do your data chips get used fast, and usually fail, but if your data chips fail, there is a chance that the Eggs will shatter, forcing you to use another one. Most people have to use several eggs, and several hundred chips to finally get a digimon to 3/5. Assuming that you do not understand what I mean by '_/5', I will explain.
To hatch a digimon, you have to put that digimon's mercenary digi-egg into the incubator, after the digimon you want drops the egg. You feed it DATA chips of the samt type as the egg, that you get from underdeveloped eggs that you have scanned for data. Depending on the digimon, you will have to use a certain amount of DATA chips at once; for instance veemon uses 10 reptile chips each feed, and biyomon uses 5 bird each feed, and kiwimon uses 2 beast each feed. When you feed these chips to the digimon, there is a gauge in the incubator, that goes up as the egg accept the data. If it is denied the gauge stays as it was, if it is accepted it goes up by 1/5 of the whole bar. You need this gauge to go up! Once it gets to 3/5, you can hatch the digimon - it will be small, and likely weak, at level 1, but you will at least have it. You cannot hatch a 0/5, 1/5, or 2/5, but you CAN hatch a 4/5 or 5/5. At 4/5, the digimon will be about average size, and will have average stats. And at 5/5, the digimon will be a noticeably larger than normal, and will have high stats. 5/5 is the digimon you want, BUT are the absolute hdest to get. You should go for 4/5, and I am serious, if you go for 5/5, expect weeks to go by, getting only 3/5, and occationally a 4/5, but never a 5/5. It takes a LONG time with MASSIVE effor and patience to get a 5/5! I advise you not to. Most people with 5/5 either, sadly, but truly, have NO life, or got them with a 'Cash Egg', where it is a 100% chance of hatching a 5/5, without fail.
if you manage to get your digi egg's gauge to 3/5, 4/5, or 5/5, then shout to the heavens in joy! you now have your own digimon! press the button near the bottom of the incubator window, to the left to hatch it; before it hatches you need to name it. The name can be whatever you want, and does not need to be unique, or untaken. Yay you!
If you do not wish to hatch an egg that already has 1/5 or higher in it's gauge, then you can press the bottom right button, to delete the egg. Yes, this not only deletes the gauge progress, but the egg itself. I would advise not to do this.
