Its all relative to the enjoyment you get out of them. Some people are happy with $3 chickens. Others are a little more serious and will pay $25 for a nice bird. Still others who are seriously serious will pay up to $100 for a bird. And then there are those who pay $1200 for a pair of Silkies.... (yes its true, it was an eggbid auction)
It all depends on what you are happy with, and what you can afford!
And everyone who raises their chickens, has every right to ask what they want for their birds. I don't fault anyone for setting their prices as they feel necessary..... I just might not buy from them!
