Local feed store recommends Purina Start & Grow exclusively until our 10 week old goslings reach 18 weeks of age. They have been on it for 4 weeks and their poop isnt firm. They are allowed to run around the yard all day so they get St. Augustine grass also. Green feed and green grass = green poop. They are growing fast a look perfectly healthy other than the loose poop. Any suggestions / comments are welcome.
