Little Problem With Pumpkin

Sooooo, my lovely ducks ate the growing tip of my jack o lantern pumpkin plant :((( lol

Will it keep growing?

I see a female flower but my vine still looks small compared to other pictures, the vine looks smaller, but it is because the stem is weirdly curved idk why lol.

Should I let grow or will it fall off?

Also I just want a single pumpkin because it's the first time im planting one, so I dont want to be that ambitious, I just want to save seeds for next year,

Thanks in advance ::))))))
