Hands down one of the easiest ways to steal an egg I found was to use a shadowmane. Use the invisibility to get through the cave and find a egg. Once you have found the egg u want u can have a tribe mate up high with a rifle and get any magmas Agro to clear the nest (this is optional you can do it solo I have many times). Once u pick up the egg jump on the shadow mane and jump to safety. You’re welcome
