You have to pick:

Do I have to sit on the egg for nine months or can I buy an incubator?

I see no reason why you couldn't buy an incubator. With modern technology we'd probably be able to build incubators that do far better than natural care.

This would actually be kinda interesting. Plus he's muscley, so he's probably good at farm work.

would you spawn like a fish or lay eggs like a chicken?

also if chicken how many unfertalized eggs would women lay a day? Also would be tasty/taboo to eat
