Bleh, just tried grafting (well, last night) shipped chicks under two mamas, one of which has been a good mama in the past. Chicks appear to be too willful and won't accept a mama (keep jumping out and running around), which makes mama(s) not graft on to chicks. Had to remove them all (shipped chicks are expensive! =)) and put them up with the ecoglow. Never had a problem grafting just out of the egg chicks, but maybe the long shipping ordeal for these made them punchy.
Well good garden o' peas, why and what are you ordering? At the meet there were plenty of folks who might have supplied you with chicks. Even with chicks , buy local.
