Okay, so I liked your opening chapter! Not a lot happens, and it's short, but those are actually good things because what does happen is interesting and unusual enough to hold the chapter up and it's short enough that mobile readers would stick through to the end. Your dialogue punctuation is a bit inconsistent in that sometimes it's perfect and other times things that shouldn't be capitalized are, so just give that another look over. Also, on that note, when the crows are arguing you say they're "bricking" with each other, but I think you meant "bickering" so just wanted to point that out.
One of the things that stuck out to me was the voice the story is told in. We have a young narrator living in modern times, but the way things are worded sometimes feels a bit overly verbose and more like something you'd expect from a more detached narrator in a 3rd person limited or omniscient POV.
The writing itself is good and you've struck a pretty good rhythm, but there are a couple spots where I had to pause and read over a sentence. When the MC is thinking about Mrs. Kelley, for example:
Mrs. Kelley always said I was a little off, but if I was being honest here--even if I was vividly seeing and hearing things again--it was her forcing us kids to call her mother when she was only fostering us for the money she received from the state.
That sentence feels incomplete. We get told a motive, but not what it's supposed to explain. So we learn about Mrs. Kelley and what she was like, but how does that connect with what's going on in the story?
The other spot comes near the end:
So, this wasn't new, but as of now: I had more pressing matters to worry about like--where will I be eating next month, or eating dinner for tonight?
This sentence just feels awkward and overly-complicated. One of the ways you can streamline it so that it flows better:
So, this wasn't new, but I had more pressing matters to worry about--like where I'd be eating next month or whether I'd be eating tonight.
Also, before I forget, the opening sentence kind of threw me off because of the way it ended and the line that followed it. I thought for a minute the story would be in present tense but then we switched tense and stayed there.
Second chapter, not much happens, but the tone of it feels better and more consistent. I do feel like it could be combined with another chapter just to make it feel less fragmented. Another thing is the last line in the opening paragraph. I'm not sure why it's italicized, if it's for emphasis or it's because it's something the narrator is thinking. If it's the latter it's not necessary given that we're already in the character's thoughts as it's a 1st person POV.
In general, it's an interesting start! The writing's pretty good and it's definitely intriguing. I will say, the first chapter did a good job at hinting at things and setting things up, but the second didn't really go anywhere. So, heading into the third chapter I wouldn't really be sure what to expect or look forward to. While the first chapter has some intrigue with the mention of whoever the crows serve, the second feels stagnant. Yes, the crows are still there, and we have a new character mentioned, but we're not told anything else, so the main question going forward after that is who Lucien is, and the intrigue built up in the first chapter is pushed back sort of taking away from the work already done to draw readers in.
To me, it feels like the story slows down a bit in the second chapter--which feels more like an unrelated interlude--because the main point of interest, which is who Kaschel is, was kinda pushed back. We're establishing Adeline's world and circumstances, but in doing so we've paused the forward momentum heading to the twist that leads us further into the story. It's probably because of how the chapters are split that it feels this way too, making things feel fragmented. Right now I know from the summary and the first chapter that there's a more fantastical twist coming up, and that feels like an important part of the story, but it's not present in chapter two and that takes the bite out of it when it does arrive.
So yeah, good start, but it might need a bit of shifting things around if you want to keep readers interested.
