The 3 ducklings seem great, they are happy with momma. The one duckling whom had the hard hatch is not doing as well. He was very weak and wouldn't lift his head. I put him inside under the lamp and have been giving him electrolytes. He is still weak but has improved since giving him drops. He is chirping. He tried to stand a few times today but mostly lays there. I would like to give him some food...but what? Mashed peas, softened food?
