I defrosted some shrimp for a project but got distracted and three days later it was time to send the expired food to an appreciative audience of seagulls and crows. Feeding most wild animals is a bad idea but many birds count scavenged proteins as an important part of their diet, and that includes dead crustaceans.
I discovered that I had shrimp allergy about 30 years ago. Probably because of the additives and stopped eating fishes.
