We're on day 12 with my BO sitting on 5 SLW eggs, and I'm planning on adding some extra chicks. (Also, I haven't candled yet, but I need to do that to see if any of her eggs are viable) When is the best time to add additional chicks? On the expected day of hatch? After her eggs hatch? Before? I can pick up the chicks any day, as the breeder lives right down the street and always has new babies ready... so what do you think?
