gollark: ```Eggs and hatchlings can become sick when they receive too many views, unique views, and clicks in a short period of time. Although sickness can occur at any time, eggs are most vulnerable when first laid. If an egg or hatchling continues to receive too many views, unique views, and clicks while sick, it may die.To “cure” an egg or hatchling of sickness, simply reduce the rate at which it is receiving views, unique views, and clicks. This may be as simple as removing the egg or hatchling from any sites you have posted it on. Since the hide action prevents eggs and hatchlings from receiving views, unique views, and clicks, it can be a useful tool at combating sickness.```
