I have 20 corgette plants growing and nearly all of them are producing male flowerheads. Will I get females with a corgette attached or shall i just grub them up?

Welcome, Al!
Extreme heat can cause members of the squash family to produce only male flowers, but that's unlikely in the UK--happens more often here in the desert! With the relatively high heat and drought you folks have been having there, I suppose heat damage might occur in an unventilated greenhouse, but I cant see any other way.
