Some genetic issues with babies?

[Wicked Storm]

So I have a two pairs of geese that seem to have some problems with babies for the last two years.
My one pair, who is on the same sort as all the other ones, have been producing babies with Angel wing. I don't think this is because of their diet because all the rest of them are on the same diet. What could be causing this?
Another one of my pairs has had babies for years. These past two years they have produced dwarves? Last year they produced one normal and one dwarf. This year they produced five however I was unable to tell before she lost the other four due to predation. They are Canada geese.
If you are wondering why I have Canada Geese I have a thread on it and I will post the link if you are wondering

I’ve no experience with geese but here is a study about angel wing and wild waterfowl. They mention the canadian geese too.. maybe worth reading

Awww
Mine is my goose I saved last year

I’ve never heard of goose dwarfism, do you have pictures?

I have a couple that aren't very good, I will get some better ones later that have her with a size comparison
The first one is when she was just starting to fly

and this one is from a few months ago. I'll get a size comparison later, then its really clear

Thank you for the reply!

I was looking up dwarfism in birds and I found two results, this study found a possible correlation between dwarfism in a mule duck and goose parvovirus but dwarfism also exists in chickens but is hereditary https://en.m.wikipedia.org/wiki/Dwarfism_in_chickens

I can’t say what caused this condition in your geese, hopefully there aren’t any underlying health concerns. I’ve heard angel wing can also be caused by genetics so that might be unrelated to the dwarf goslings.
If it was parvovirus causing the dwarfism you would probably see heavy losses so that’s probably unlikely that that’s the cause?
Random genetic mutations can sometimes occur, maybe that’s what’s going on? In chickens it doesn’t seem to cause health issues “I only just found out about this so I may be wrong” and is sometimes seen as a positive for a number of reasons. If your geese are all healthy and they have the same advantages “lower feed requirements, better heat tolerance” you may have been dealt a good hand.

Yes I wouldn't think it's parvovirus. I'm just confused because it's happened for the second year in a row now. I'm not complaining because to me it's kind of cool Sorry for the late response!
