A bird in the hand is worth two in the bush.
Don’t count your chickens before they hatch.
One swallow does not make a summer.
What’s good for the goose is good for the gander.
Wise as an owl.
Eagle eye.
Kill two birds with one stone.
Like water off a duck’s back.
Like a duck to water.
Madder than a wet hen.
The goose that laid the golden egg.
Something worth crowing about.
Light as a feather.
Hen party.
Jaywalking.
Like a duck on a June bug.
My little chickadee.
Naked as a jaybird.
Nest egg.
Run around like a chicken with its head cut off.
Strut like a rooster.
Stuffed like a Christmas goose.
That’s just ducky.
Watch like a hawk.
