Does "was chewing on the ear of a third" mean "(Sow 44733) was chewing on the ear ?

Does "was chewing on the ear of a third" mean "(Sow 44733) was chewing on the ear of a third"?

And "sported abrasions" means "had abrasions"?

Context:

ELDRIDGE, Iowa — Sow 44733 had broken the shoulder of one of her pen mates, rousted another who was huddled in the corner and was chewing on the ear of a third.
Other sows in the pen sported abrasions, torn ears and bloody tail stumps — all souvenirs of her attentions.

She was chewing the ear of a third pig.
Yes, they had abrasions.

[NewHopeR]

She was chewing the ear of a third pig.
Yes, they had abrasions.

Thank you.

"who was huddled in the corner and was chewing the ear of a third" looks like the rousted pig (the second was chewing on the third".

I know what you mean, but it's pretty clear that #44733 was doing all the aggressive stuff.

A comma after 'and' would remove the ambiguity.
