I enjoyed your second chapter, and I think it develops Joe's world very nicely (I read both the original and the revised version you linked to in your most recent post, by the way).
I think the added passages and details add greatly to the immersion of the reader into Joe's situation, and in fact I think you could go still further. I think you could move from a mostly 'cinematic' viewpoint to an almost completely 'character' viewpoint in the latter half of the chapter as Joe strives to make sense of this new place he's been thrown into, and the people and situations he's dealing with.
I like Nats very much; she has tremendous potential as a mentor and friend to Joe and a foil; there's already a lovely banter developing between them and there's much drama and humour to be got from the slightly naive Joe, a 'stranger in a strange land', interacting with the more knowledgeable Nats.
It will be interesting to see where you take the 'culture' of the island. It's handled sensitively here, and I hope that the agency and independence that Nats shows in this chapter is typical of the way the gender roles interact.
There were some occasional moments where I wondered about specific choices of words - only a few. One that springs to mind is the sentence: 'As she waved and shouted her greeting, her stomach bulged ominously under her T-shirt.' It's the 'ominously' that brought me out of the story. Joe doesn't know about pregnancy, so would have no preconception to make his reaction to the sight of a bulging tummy be that it was 'ominous' (and even if he did, the negative connotation of 'ominous' seemed odd here. If it is, indeed, ominous (within the setting of your world) I think it needs more context.
As someone who keeps chickens myself, I really enjoyed the feeding of the flock. 😁 It rang very true, especially Joe's reaction - which I've seen myself with friends who've fed mine... and I only have a few!
In my view, with even more of Joe's inner thoughts and feelings, especially in the latter part, and some re-visiting of the occasional word or sentence to focus in more on the exact meaning that's intended, and you've got a very strong continuation of Joe's story here.
