Tulip carnage

Animal damage or rainstorm damage? What do you think?

It seems suspicious that only red tulips suffer this damage. That makes me think it is an agent of some sort like a squirrel. On the other hand, one might contend that red tulips are inherently more likely to be damaged by rain due to a weakness in the plant tied to the color (breeding red plants breeds weak plants, for instance).

I just want them to survive to flower and be pretty to look at.
