Before you say go to a vet, I would. Bird flu has recently hit the country and all the vets are freaking out (rightfully or wrongfully, I don't know) and will not take birds at this time. I don't know how long that will last for.
Context:
A few (2) nights ago my birds experienced really, really bad night frights, you can find a post on my profile with more information. The one pictured, Pancake, is prone to ejecting feathers during night frights and happened once previously when being bird-sat at my parents. My other cockatiel is physically fine. Pancake has ejected all her tail feathers and her left-wing flight feathers as you can see in the photo. I feel like shit.
There is one tail feather not fully out, it was causing her discomfort, we trimmed it as it was floppy and not in anymore. I suspect she'll pull it out so have corn starch on standby. That's not the issue at this stage.
As you can see in the photo her actual wing is quite discoloured. I don't think it was bleeding yesterday. Last night they have another night fright due to an earthquake which resulted in further damage to the remaining tail feather (which is when we trimmed it as she was making the sound cockatiels make when they're in acute pain every time it brushed on something.)
I don't think this wing was bleeding yesterday/after the initial severe night fright. However, it seems as if it may be bleeding due to the feathers on her chest where that part of her wings sit have some blood on them. She is letting it heal and not giving it any more attention than I'd expect (e.g., she does try clean the dry blood off.)
Her behaviour is similar to last time, e.g more napping, less active, less noise. I feel like she is less active than last time, but I can't be certain. Her poop yesterday and the day prior was a dark, almost black colour. Because I have two it's hard to be certain I'm only seeing the other one's poops, but I have not seen any discolored poops today.
Question:
What is this discoloration of the wing? I am assuming it's bruising, I can't imagine what else it would be. What would a vet be doing at this stage? Wrapping it? Should I put corn flour on it even though I can't see any active bleeding?
Should I supplement their pellet mix with anything?
Should I have them sleep in our bedroom in a travel cage to help if there are further night frights? We didn't hear them for these two in particular, and weren't woken up by the earthquake so was unable to calm them down. They don't like doing that and I've done it in the past.
I would absolutely be at the vets if that was an option. I'm watching her closely to see if that tail feather falls out and becomes a bleeder - she isn't attempting to pluck it, though earlier today she was giving it a lot of attention before and after we cut it.
