My female 10 year old Pilgrim Goose has been feeling a little down..I might say depressed, not eating well and watery poop. They free range, have drinking and bathing water fruits, veggies, cracked corn and share my goats alfalfa. No sneezing or watery eyes just generally not herself. Her life long mate is doing fine and acts as if nothing is going on. In ten years neither of these geese has ever acted funny. Except once when the goose had a problem laying her first egg of the season. Any ideas would be greatly appreciated.
