To know how much time need to the next feeding just do the next. Look the Food number# then that number multiply x 10, then divide /3600 and the result will be the number of hours until the next time need to be fed. F.E the food number is 1850.5 1859.5x10=18595 /3600 = 5.1 hours
A fire wyvern is one of the best you can have because they are resistant to fire damage so alpha wyverns are much easier to kill same with all the wyverns they can't hurt each if they are the same element but the bite attack still works on all wyverns keep this in mind

"YEEEEESSSSSSS DRAGONS YEEEEEAAAAASSSSSSS"
Wiki: "You must go into its nest with a fast bird, steal an egg, run away from 50+ wyverns trying to kill you, go back, get a female wyvern, knock it out, get its milk to feed your baby wyvern, raise your baby wyvern for many real life days, never sleep, starve, make sure you got lots of milk, get arthritis, play non-stop, never see society again, boom you have yourself a wyvern."
