A couple days ago one of my Bibbed Hookbill females died. I was shocked! She seemed as healthy as could be. This morning another one is dead. They were hatched in April. They came from Holderreads. They seemed great from day one. We only lost a couple ducklings out of 60. They are full grown and live with the big flock of ducks. There are probably close to 100 of them all together. Many different kinds, and several different ages. They are in a big yard during the day and locked in a pen at night. The yard was just moved to a clean spot yesterday. They are on a diet of layer feed. I saw absolutely nothing to alarm me yesterday. Nobody seemed slow. Today she is dead. She has no mark on her. I can not feel any lump or scar. She seems to be healthily heavy. The only thing wrong I can find is that she is dead. I only have 4 Bibbed Hookbill girls left now. Even more upsetting to me than the fact that she is dead, is that I have no idea why. Any thoughts or suggestions?
