A thread of some animals who sacrifice a lot before having babies.
1. KIWI
Let's start off from Australia. While other birds lay many eggs, kiwi lays just one egg at a time. But the one egg is equivalent to 20% of her total body weight and almost half of her size. That's like an adult human carrying a 6 year old baby in their belly.
When the egg is stressfully laid, they still invest 70-80 days to incubate the egg. That's about time 2 the time ostriches spend incubating. Incredible!
