Any birds i have sold i get contact info on the person i sell to so i can check up on them and let then new owners know that for any reason the birds dont work out i will gladly take them back. So far i have had one plymouth rock bantam rooster that i rehomed get eaten by a predator, all the rest are happy and healthy in their new homes. I may be bugging the new owners by checking on the chickens but at least i care about them enough to do so.
