Those toes appear necrotic, so I would expect her to lose those toes. Unless it's severe bruising? You'll know soon. If the dark color expands, it's necrosis. If the dark color recedes, it's bruising.

I personally prefer to give antibiotics as a prophylactic measure when there's this degree of trauma and necrosis, especially since the skin was broken.
But it's your choice. Some prefer to only give antibiotics after an infection forms. I prefer a proactive approach, as it's very easy for the bacteria-ridden necrotic tissue to harbor bacteria that's then transferred to the live portion of the foot/leg.

I would also remove the floor grate or cover it with paper towels or newspaper. If it's necrosis, she'll lose sensation in those toes very quickly and she'll be at risk of getting them caught up.

Also, if you're certain those toes are necrotic, I would dip the foot into hydrogen peroxide for about 30 sec 2x daily. (Or a bit longer - around 2 min if you have an established infection) This will cleanse away bacteria and the full strength hydrogen peroxide will speed tissue death in the dying toes. Then, pat dry and apply antibiotic ointment.
I usually take a little piece of vet wrap (also sold for humans as self-adhering bandage) and I'll make a semi-loose sleeve to go over the affected limb. I'll apply a liberal amount of antibiotic ointment and then the little sleeve to hold it on the leg/foot. (Otherwise it mucks up the feathers or just wipes off.) I'll leave it on for about half an hour, then remove the sleeve and wipe off the excess ointment. I'll do this 2x per day. It really helps when there's an established infection, as the antibiotics are absorbed through the skin (and it softens the necrotic tissue too, which speeds deterioration so it falls off faster.) But notably, I've never used this procedure on a less-than-tame finch. I'm not sure if it would be more upset than it's worth. So that's something you'll need to decide.

I prefer ointment over cream as ointment tends to stay on better.

That means she's likely through the worst of it.
Once the dead tissue falls off, the stump can finally heal. So hopefully it's all downhill from here!

How is the stump looking?
Has she had any issues with infection? (e.g. redness, pus, etc.)
Or have you been able to keep it infection free for the most part?
