I'm trying to get a chieftains owl and I'm wondering if you hatch a first gen owl with another first gen will the talents be the same so you can multiply them?
No idea. I do have a chieftan's owl if you want to hatch though. My guess is they do not "multiply" per se, but you'll have to find a pet expert. Let me know if you want to hatch.
If you hatch 2 first gen pets of the same type they will always have all same talent pool as a first gen. Talents never double, each parent gives 5. Since they both have the same 10 and talents cannot repeat they always get the same 10. For all practical purposes you will have a new first gen.
