Animals that have been bred give you more loot

The babies of animals you have bred should give you more loot than ones you find wandering around!

aka once bred: cows will give you milk and they will give you more meat or leather, get more meat (+ maybe something else?) from pigs, get more feathers and get eggs from chickens, get more meat and wool from sheep, etc.

And perhaps there could be a special/more rare version of the animal you can get from breeding? Even if its as simple as a different coat colour, it'd be nice to have a goal/trophy aside from food when farming animals!

It would be nice to have a rare brown chicken, or a black and white cow, or a sheep with horns that I could show off at my farm!

It would make farming the animals a bit more useful, cause right now, unless Im specifically farming leather or feathers, I don't really have a need to make a farm aside from aesthetics. I can get plenty of meat from running around and killing a couple herds, or from vegetables and wheat.
