My girlfriend is raising 6 baby ducklings and when letting them swim in fairly shallow water one of them was pushed under and held under by the bigger ducklings and became almost lifeless. We grabbed him out of the water and tried to get him back to life. We were successful however now he is isolating himself from the rest of the ducklings and is panting heavily and will not drink or eat food. We do not have much experience with ducks but I really don’t wanna see him die. Any help or suggestions would be great. He deffinetly had water in his lungs but we got him to spit it out and he started breathing better but it is taken a turn. Please help
