Okay, so this is gonna be a long one. I never properly posted here for advice, but better late than never, right? So a while back (i've honestly already forgotten how long ago - 6 months is my best guess) I came into "ownership" of a male society finch. Okay, legally he's my mom's as she adopted him, but it was under the conditions that he went into my care, and mom gives me free reign on it as i'm spending my money on him and he's in my room, and I'm the bird person of the house. (for context - I'm almost 20, am for the most part financially independent, I just live with the parents and brother still) He's super sweet and chatty, and while he doesn't come out often (typically only for a cage deep clean, or for a beak trim, context below) he's very active and aside from his beak condition seems to be in good health. He's on a free-fed diet of roudybush pellets and a seed mix which he picks from both dishes pretty equally. I'm still trying to find fresh foods that he'll actually take, as he seems scared of just about everything. He also has a bath attached to the front door of his cage which he dives into at least twice a day it seems, haha. We adopted him from my work, actually, due to his condition. No matter what we did, his little beak just kept overgrowing - I have no photos at the moment, because thankfully it doesn't grow nearly as fast as it used to, but it looked like he had bulky 'vampire fangs' on the sides of his upper beak, and the bottom beak looked like it had a little garden shovel folded in half growing out of the front end. We lovingly nicknamed him snaggle for a while, until mom named him Buttercup. From what I researched, it likely was a combination of poor genetics and a subpar diet - so I'm hoping that the better diet and access to a small sand perch (fear not! It's only one, and I keep it away from his preferred sleeping spots to discourage him spending all day on it - he has a manzanita perch and a fir perch that he uses 95% of the time.) has helped the problem. I'm wondering if there's any other things I can do to help his beak problem? I don't like having to have it trimmed more than absolutely necessary, because it obviously stressed him out, and that much stress on such a tiny heart is less than desirable. Additionally, I'm wondering what most of you finch parents recommend to keep your little beans occupied and mentally active? I feel awful that I haven't found much to keep him entertained yet. I've tried toys he can pick and pull at, left them there in cage rotation for months, and he never went near them. I've tried treat toys and simple foraging (not parrot puzzle level, more like.. look behind the slightly obscuring toy kind of 'foraging' just to see if he'd even go near it) but the little bugger won't even touch treats, I don't even think he touched millet. I'm also looking to upgrade his cage a little more asap, as what he has isn't cramped, but more space is always better. I have one in mind, I'm just hoping there's some things I can add to his space so it's not so empty feeling - unless that's a good thing? I'm more versed with the parrot family instead of little softbills, so it's sadly still unfamiliar to me. Aside from his food bowls, water silo, and perches, he's only really got his bath, a nest (which he refused, and took up sleeping in his foodbowl instead, haha) and a hayball in hopes he'd pick at it - he hasn't touched it once since bringing him home. Honestly I'm open to whatever recommendations you guys have. I feel like his conditions could be improved, and I want to know what I'm doing wrong, and what I can do to head in the right direction.
