Lovebird bit my chins foot

I'm dumb, I had the birds out while cleaning Delilah's cage. My lovie got in the cage and bit Delilah's toe. I tried to find the wound but can only see blood. Is there anything I should do for itor put on it? She was running on her wheel and chewing on her toys so I assume she is ok? But it must be sore, poor baby.

I feel so bad, I wasn't paying attention but my lovebird has never attempted to get in her cage before.
