DH ordered four Japanese phoenix, but was mistakenly sent Japanese bantam. Three have died & the fourth one is sick. We have not had a problem with any other breeds or ages! Our extension agent had us put them on sulmet & I thought this last one was fine (been two weeks since we lost one). He told us that Japanese just aren't hardy. DH would love to get some Japanese phoenix, but losing birds is heartbreaking to me. What has your experience been?
