I’ve tried to but he won’t eat them. He’s become very picky at what he will eat. Should
It be plain yogurt or Greek yogurt or something else specific for geese?
Dairy isn’t digestible to birds, so it causes a lot of stomach issues.
But a good cultured “live” buttermilk or Kiefer has a lot of beneficial bacteria and yeast which consume most of the lactose so it isn’t as hard on them.
Plain yougurt and even most big brand Greek yougurt is so pasteurized there isn’t much left alive in it, good and bad, so I’m not sure how much use it is.
There’s also probiotic supplements, the trick with those is to get the highest percentage of organisms + a higher number of species. Certain companies also have better quality. Most have a range of 1 to 9 species, 1 being not really worth your money. Dumor probiotic is decent all around, probios doesn’t have as many species but there product is fresh and good quality. Savachick has one species, it’s not worth the bother.
Then there’s brands marketed towards parrots, they get a bit pricier, healthy gut avian probiotic and vetafarm probiotic are good ones, vetafarm comes in a tiny bottle though, so you’re not getting much.
There are human probiotics which work for birds as well as they do for us, but not all are made equally, and the effective ones can start getting pricey, Dr. Tobias deep immune is a good brand I’ve used, it’s moderatly priced, the best is visbiome which is what doctors want people to take when fighting clostridium, I have no expierience with it though, I can’t afford an $80 probiotic.
With any probiotic the key is trying to make sure it’s alive and as much of it makes it to the gut past the stomach acid as you can get, hence the higher count probiotics being more effective.
I like to mix several probiotics with some kiefer and drizzle it over soupy mash made fom feed mixed with water, it’s the only way I can get mine to eat probiotics or kiefer that doesn’t involve a syringe, but chlorinated water kills the probiotic so bottled non chlorinated water is more potent to use when giving probiotics.
There’s also culturing the probiotics themselves by mixing a few probiotics together with some water and honey and warming it to 90 degrees for 24 hours in a vacuum sealed dark container, but that is hard to do + without being in a lab setting there’s a big risk of culturing bad bacteria with the good.
