DHV types 2 and 3 are recognised as separate entities because they induce hepatitis in DHV type 1-immune ducklings, they are now classified as member of the Astroviridae family. Molecular characterisation of the DHV-1 genome recently showed that the genome organization classifies this virus as unassigned species in the family Picornaviridae. DHV-1 has, since the first outbreak in 1949 in Long Island, been reported to infect ducklings worldwide and is of most economic importance to all duck-growing farms because of high potential mortality when infection is not controlled.

So far, three different viruses, duck hepatitis virus (DHV) type 1, 2 and 3, have been associated with these disease conditions. Duck Virus Hepatitisĭuck hepatitis (DH) is a highly fatal, contagious and rapidly spreading disease of young ducklings from one to 28 days of age. Greater attention needs to be given to the study of this source of disease. It seems likely that viral diseases will assume greater future importance as causes of disease in waterfowl. The infectious diseases described here are the most common viral diseases seen in domestic waterfowl species. There are many diseases that can affect waterfowl species. Additionally, environmental conditions may also influence disease manifestation in domestic waterfowl. One feature that is unique to waterfowl is that their environment usually involves the presence of man-made or natural bodies of water, and this may enhance the co-mingling of free-living waterfowl species with the domestic flock and ultimately, promote disease transmission. Steel 4s are roughly the equivalent of lead 6s and just right for small ducks, but marginal for large ducks, in my opinion.Although chickens and turkeys comprise the majority of poultry species seen by the veterinary practitioner, occasionally waterfowl such as ducks and geese are encountered. Steel 2s are roughly the equivalent of lead 4s and about right for large ducks in my opinion, though I have been shooting some 3s with good results lately. Also, I have seen nothing that motivates me to pony up big bucks for the new "high tech" loads. If you are shooting them off the end of the barrel, you can kill them with about anything, but. If longer shots are expected, I break out the 10ga and the BBBs. In the several decades since they started making us shoot not-toxic shot, we have tried everything from 2s to Ts (even a few Fs in the brief period before they banned them) and settled on BBs over decoys and at moderate ranges. We shoot a lot of Giants out in these Illinois corn fields.

On the other end of the spectrum, Giant Canadas can go up to 20 pounds. There are a half dozen races of Canada geese, the smallest of which are not a lot bigger than a mallard. You don't say where you will be hunting geese, which makes a difference, but I am assuming large Canada geese. Steel BBs are roughly the equivalent of lead 2s.

I gathered from your original post that you are limited to a 2-3/4" gun and fixed full choke.
