I have two pilgrim geese, 4 months old and hand raised. The gander is having horrible diarrhea but is acting normally. The 'left overs' are very watery, brown/yellow with white... I just cant figure out whats wrong! I know diseases can move quickly in birds, so i need to move faster than it! I noticed him having this about 3-4 days ago, it got better yesterday but now it's even worse. Tomorrow i'm getting de-wormer for both geese. Advice? These are my first geese so i am inexperienced. Thank you in advanced.
