Re: Duck egg production numbers down / the ducks aren't laying as many eggs as usual
Thanks, JJ and AnneZ.
Someone pointed out to me that a decrease in egg production in domestic ducks and geese is, in face, one complication of H5N1 in these birds:
DUCKS AND GEESE
Incubation period
3-7 days
Clinical signs
—Signs of depression, inappetence, and diarrhea similar to those seen in layers
—Swollen sinuses
—Neurologic signs in younger birds
—Sinusitis
Complications
—Decrease in egg production
—Sudden death
—Surviving birds are in poor condition and resume laying only after a period of several weeks
Case-fatality rate
As high as 100%
