My daughter hand raised 6 Chinese Geese, 3 whites, 3 brown. They are so sweet and social and they know their 'mama'. They are now 4 months old, beautiful. BUT, just recently we lost two of them! They suddenly began acting lethargic, weak, hardly able to stand and then died overnight. She thinks they got some of the chick starter which is medicated, but not much. They have been eating all-flock mixed with scratch. Three of the remaining seem alert and healthy, one is looking a little less than 100%. We think they weren't getting enough greens because they were in their pen most of the day. Please, any ideas, we don't want to lose another one! these are her babies.
