You are responsible for caring for the birds in your birdhouse, and they rely on you for their health and comfort.
When your birdhouse gets too hot (because you're not checking it to keep it clean), your birds will stop laying new eggs. Now, when you do clean the birdhouse, egg-laying resumes. However, you've lost out on the eggs that could have been laid for you during the period the birdhouse was too hot, and the coins you would have received from selling said eggs.
We'll send you notifications when your birdhouse is starting to get hot, and we'll send another when the temperature inside your birdhouse has passed the critical temperature (42°C), at which point egg-laying stops.
