as stated by Endorsi the Breeder didn’t feed itself snakes it fed snake strands to its kids, Endorsi. Then after she became the best, sold her off!
Androssi wasn't SC's kid. Not any more than any other princess candidate. What are you talking about? The only snake byproduct kids seem to be the LPB twins, which actually supports that SC = SS.
Why wouldn't a snake that creates other snakes (also known as 'breeding') not be referencing it's own baby snakes as 'kids' as it raises those snakes, feeding them parts of itself?
The horn on Endorsi’s head must be a by product from the snake power she absorbed from eating this snake strands.
But, let's say you're correct. Why don't other princesses have horns? Androssi wasn't his only creation. Do ANY other cultivated princesses have horns? Hell, does SC itself have horns? That's rhetorical, because no.
In any event, the main point remains. It was so similar she froze up. She suggests the snakes are slightly different upon closer expectation. That's it. She doesn't even confirm they are different entities. She leaves that door open. That's called a literary HINT.
Nothing has really changed, other than your suggestion Androssi might have eaten snake, which still seems unclear.
