Golden Animal Products and the Ship Everything Achievement

[zealous nova]

This is a two-fold question. I got my prize winning chicken and cow after they started giving me large egg and milk respectively.

1: Is there a way to get the smaller versions without getting a new chicken and cow? Or do I need to suck it up and get both almost right before the Festival and attempt it?
2: Does it even count for the Ship Everything Achievement or am I just wasting time and effort?

I ask these questions because I am missing 2 spots (I'm already accounting for the Ostrich and Buffalo of which I know I'm missing). Thank you.

If you don’t feed them, don’t pet them/remove an autopetter, and let them outside in bad weather for a few days they can produce small products when fed again. If you don’t want to mistreat your animals then I’m pretty sure the only way is to wait for the festival next year. I don’t know about 2, sorry
