Intelligence

Better to be cuckoo
sitting on the wire 
introducing spring.

Crow knows
when the chicken
has laid an egg.

-- it blows his world apart

To Bunx's point about the crow getting shot...perhaps that's what the reading is intended to be. 
I like how the poem opens, but the rest of it is hard for me to decipher, and even if it's about crows getting shot for stealing eggs in the spring, I don't see the poet's intent here.
Perhaps some more clues are needed.
