I received a batch of Rhode island Reds and Dominiques from MM on 3/10. Many of the Dominiques became ill 12-14 days later. They are quarantined, but alive. Can't find anything definitive regarding the long-term prognosis. Anyone? If they survive, I'll always have to keep new chicks under 6 weeks away from these survived adult birds? Will survivors be poor layers or maybe not? My husband really doesn't want to euthanize them. Any info is appreciated. How uncommon is this AE outbreak? Thx.
