Early rising mollusc?

Birds?

squirrels have nibbled some of mine. could be rabbits too.

Mine are being eaten too. I can only think it's slugs.

Mine also, some have had the heads snapped off but flowers not eaten, never had it happen before...

Mine have been snapped off too...and I know EXACTLY who is the culprit. Great big hairy mad Labrador!

Have seen sparrows having a go at them in the past. Blue tits also will go looking for insects in the flowers and snap them off. They do not eat the flowers though.

Thankyou to all. I think I'll just accept it as part of nature as we all do at times, but haven't known it before to this extent. It's been very cold even here in Devon so I didn't think slugs.
