Oh, poor geese. So glad you are taking an interest in their well being. Did you know a goose can easily live for 100 years, and lay for over 80 years?
(citing the BBC, but can't remember which article it was - average goose lifespan is shorter) I think the oldest recorded age of a goose is 140 years. They have surprisingly long memories and a very complex social structure. To think that this animal could outlive the human that cares for it, makes me feel that geese, more than any other livestock, deserve extra special care. At least that's my thoughts.
By the way, welcome to Permies.com
A photo of the geese would be a big help trying to diagnose what's wrong with them. Until then, I can toss out some theories.
My first thought was it's approaching molting season (at least it is here) so they will start to look miserable very soon. Then reading more of your post, I see their conditions have not been ideal, and I suspect this years molt will be very stressful.
Because of their long memories, geese are very susceptible to depression (in my
experience), and can pine away and die if something stressful happens - like loosing their nest, or moving home, or general unhappiness.
... is the condition of these geese from them beating each other up, from predators harassing them at night, or something else I'm not thinking of?
Yes
Probably all of the above. If an animal is weakened for any reason, predators will move in, even big critters like geese can be attacked by raccoons, cougars, eagles, whatever's common in your area. They will fight more when stressed, especially as it's breeding season. And of
course they are grumpy from the molt, which makes them fight even more. If the lack of shelter isn't doing them direct harm, it will certainly contribute to their overall ill health.
What are anyone's suggestions for dealing with this situation as I would like to continue to be friends with them
How to say this gently? I'm not sure how. This is your situation, and there is no way I could ever get all the relevant nuances from an internet post. What I have to say may not be relevant to your situation. I would like to say something from my personal experience, and you can take what you want from it. My personal experience has been that people who cannot treat animals with at least the most minimum basic needs (food, water and shelter - although I'm also fond of safety from predators, I don't consider it a basic need as they don't have it in the wild) also don't treat humans with a great deal of care. Although I've sometimes found myself friends with people like this in the past, I find any relationship I have formed with them don't last. But like I said, your situation, you need to decide what's best for you. All I can do is offer my thoughts.
Did I do that gently
enough?
Getting back to your options. This depends a great deal on where you live. Could you give us some idea of what country/region you live? We could tailor fit our answers to suit your location. If you don't want to, that's okay too.
Ideas:
-offer to take care of their geese while they upgrade their facilities then when they come to collect their shabby geese, apologize that they died and these healthy geese are other geese that you had bought somewhere else, here's some money in compensation. This is not the best option as you may get a bad reputation for killing geese.
-You may live somewhere where there are laws requiring basic care for animals - food, water, shelter, and (locally to where I live, the law includes) safety. Where I live there are different laws for livestock and for pets, but the line is blurry. The police or
local bylaw officer may be able to help, but every
city seems to be different in how they handle this sort of thing. This may or may not be anonymous, and it is wise to gather evidence to support your point of view (photos, a log of events, statements from the vet, stuff like that) before going to the authorities, in case you live in a more litigious part of the world.
-The SPCA, or your local animal rights activist organization/ animal shelter, may be willing to step in. Where I live they have a huge influence and in many animal rights cases, much stronger resources than the legal route. Tips to the SPCA are
usually anonymous, and they usually tell the farmer/animal owner that "a neighbour made a complaint about..." In many cases this may end with the death of the animal, especially with livestock. Some branches of the SPCA require you make a donation to cover vet bills before they will take your complaint seriously, but I doubt that's the norm.
