your never going to hatch them all. Some dinos, I have 100 or more. Look at what the dinos stats do for your fighting and build the ones that will help you most. also look at how long it takes to hatch them. don’t waste dino bucks on the 2nd, 3rd and 4th hatching chambers to pop out fast hatching dinos. use them to hatch the 5-7 day dinos. save the first chamber for the quick hatching dinos.
dna will be a problem later on. the big dinos will cost 50,000-70,000 a pop. so dont waste dna. try not to buy dinos at full price wait for 10%-15% off if you can. as long you dont have one in your inventory, you can always purchase one on sale even if you dont have a free hatching chamber. it will throw it up into your inventory and you can hatch it later.
