I have two baby ducks and one is older (yellow) and one is younger (black). The older one is breathing harder. I thought it might be hot so i turned the heat off (its quite warm in the house) and put fresh water in thier. The yellow one is still breathing hard the black one seems fine the yellows one feathers are changing white since its almost grown. I try to keep the shavings dry but the black one jumps in the water and gets the shavings all wet. Im worried about the yellow one!!!
