I'm gonna give you 3 TIPS , which are not covered in ARK-Wiki :

1- Eggs weight 50 , so take care, because for stealing the egg you have to act fast.

2- For getting the Milk, beside knocking out female Wyvern, killing an Alpha Wyvern with Rocket launcher will give you lots of Milk.

3- You can't put the Milk in the fridge. Use preserving salts.

Good luck !
