I am new to geese, have a 5-7year history with chickens and ducks. I sneaked in a couple of day old pilgrams on my wife this spring and she hasn't divorced yet. I have really enjoyed them but my male limped a bit about a month ago and seemed to get better and a couple of weeks ago got much worse. I didn't know if I was going to have to put him down cause he wasn't getting around well and would get himself into situations he couldn't get himself out of. I did some research and found out that ducks and geese need niacin and selenium. I found out that brewers yeast contains both so I started to sprinkle a teaspoon on their feed daily and in about a weeks time his limping stopped. I'm not sure that is what got him better but that was the only thing I did different. My game feed has niacin and they free range all day so I wasn't sure why just one bird was having problems. I will post pics of my pride in joys soon to share with you. Just thought I'd share this everyone here on BYC.
