selling is great... then you get money for feed. and supplies etc. for your other chickens. you can give them away if thats what floats your boat.. but i myself Sell the ones i dont use (plus.. my chickens are show chickens. if i was to give one away with the bloodline i have.. i'd be giving away 100-200+ dollar chickens
I've been to a couple of poultry/small animal livestocks. If someone is looking for new blood for breeding, and it is a common breed like a RIR, and they are interested in the particular breed you have for sale you might get $10.
I've seen chickens that have won a prize at the fair sell for $30, so DT Chickens must be one heck of a salesperson.
