Probably my Barred Rock hen, Pauline. She was worth every penny of the 8.50 I paid at auction for her. She is bossy and mean, and closely related to a wild boar both in stature and hunger, but she is a dependable layer and is the undisputed "boss" of our coop.
Just for reference, here's a list of our chickens and costs of each:
Scooter: Red standard cochin roo: 6.50 from local seller
Beatrix: our pet andalusian hen: 7.50 from local seller
NeeNee: our partridge silkie hen: 5.00 from local seller
Charity: our dud RSL pullet: 6.00 from local production farmer
Trudy: our RIR pullet: 3.00 from a local seller
Chester: our BR boy: 3.00 local seller (came with Trudy)
Sunshine: disputed silkie hen or roo: 5.00 as hen at auction
Yumi and Naoki: Pharoah quail: free from two tiny eggs a friend gave me : )
3 Bobwhite quail: 9.00 total or 3.00 each: local breeder
Ginger, Marion, Martha, Persiphony: OEGB hens: FREE!! From local man who was moving...he was obviously nuts! : )
Pierre: OEGB rooster: FREE as repayment for original free OEGB boy "Monty" who the neighbor's dog killed....I want Monty back...so I have:
VIGGO: Monty's juvenile son who is growing up to replace useless Pierre. Cost for Viggo: FREE! I incubated the little fella with his two sisters, Veronica and Violet. As well as a horribly ugly cochin silkie cross (ScooterXNeeNee) named LeeLee.
I also have 5 BR chicks that costed me 2.00/dozen eggs to hatch...so...since out of a dozen I only hatched 5, that would make them worth about .40 cents each according to what I paid....and two who knows what white birds that came from RIR eggs I got for free....
Whew! I just wanted to list my birds I guess....
