Very true, sadly I did spend gold to speed bred it. About 20 hours ago, I bred this egg and took a screenshot, intending to spend gold to hatch it. But the game shut down straight after the screenshot, and I haven't been able to log on to the game since... (The game shut down numerous times, each time 1-3 days for me. I did raise a ticket months ago, still not fixed). I have tried rebooting my device.
Not sure if it's the chirping egg.
If this is the Chirping egg, I used Gold and Unicorn.
