Single post in Your Guide to 90%+ Breeding Pairs

I'm so confused-I'm getting a message that's saying this about this though I put up two Seasonal Turtwigs in the Daycare (one level 32, one level 2) of different genders and OT. The message I'm getting is The Pokémon are inseparable. 90% * * This represents a best-case scenario. Other factors may result in less Egg productivity than indicated here. All it prouduces are Turtwig eggs. What's going on?
