if you don't have any, make it night and use a dusk ball), go to seed finder on RNGReporter, plug in the iv's of the pokemon you just caught(clearly if you don't have an ar, you would use stats instead), press ok on the delay that seems reasonable(most of the time you only get one choice), then select DPPt Breeding at the top and click generate(make sure your NOT searching for ivs, shiny, or nature), find the frame that most suits the egg you hatched. this is why ar is recommended, it saves lots of time, but it is possible without it. if you do have an ar, calibrate more than once, if not, then just calibrate once. hope this helps.
