How to get the new egg pet (Pet Crow)

Step 1. Go to a nest with eggs in it, click on it, and click "buy".
Step 2. You will go to a screen where you customize an egg. If it's not floating, keep Xing out and going back to the egg customization screen until the egg is floating.
Step 3. Wait for 72 hours.
Step 4. You now have a Pet Crow!

Note: I found out about this on the AJ wiki. I bought a floating egg, but it hasn't hatched yet, so idk if this works.
