I have a few raptors and a couple of fertile eggs due to the fact that they can incubate at beach temperature, where my base was set up. I walked out the house and noticed a second baby raptor (I birthed a claimed one days earlier in-game) and was surprised that it just showed up and I didn’t have to campfire-incubate like normal. Remember to spay/neuter so you don’t overpopulate for what you can’t account for. But if they lay fertile eggs they can be preserved for another day...
