Sunflower Analysis Week 10 (Some sad stuff)

Hello everyone,

So I decided to try to plant some sunflowers outside..., and... well, I planted two outside near my garage, and I'm pretty sure someone came along and destroyed it.

Also, I planted two of the better growing ones near my patio (where it's nice and warm), and the rabbit in my backyard ate the heads off :(. So I guess I now have 3 sunflowers left. I don't know what to do with them, they're growing pretty well. I don't know if I should repot them in larger pots with better soil or I should just leave them be (this current situation forces me to stay at home rather than at Home Depot).

I'm not sure if the two who got their heads eaten off can regrow their heads (they seem to be doing well).

The two with eaten heads off. I wonder if they'll. grow back?

I wonder if its based on the type of sunflower?

I'll be back with some research on the matter.
