⚡ What Birbegg does
Every 5 minutes, all your eggs advance their hatch time by 150 seconds. Each time there's a 30% chance the advance is multiplied by 2.5, making it 375 seconds.
The wiki notes the ability is similar to the Bald Eagle's. Only the multiplier changes with weight; the 5-minute timer, the 150 seconds and the 30% are fixed. Some wiki trivia: it is one of only two pets with a 0.1% hatch chance (the Raccoon is the other), its hunger is 1 less than 50,000, and "Birb" is the only pet name that isn't a real word.
