Are all correct below? If any are correct, which ones--and how would you write them?

the goose's trail (sing. possessive)

the geese's trail (pl. possessive)

the mouse's path (sing. possessive)

the mice's path (pl. possessive)

the mouses' paths (pl. possessive)

the deers' path (pl. possessive)

the deer's path (sing. possessive)

How many deer have you shot?

Thank you.
victothe mouses' paths (pl. possessive)
victothe deers' path (pl. possessive)
Those two are not correct. 's is added to plural forms which do not end in -s. So, it's mice's and deer's.
Thanks, five.
