I noticed today that one of our 2 1/2 week old ducklings (a Welsh Harlequin) will kinda crawl around to get to food and water. She will stand and walk around a little but it is like she prefers to scoot along the ground. I switched them all from a 20% starter this morning to a 15% grower/finisher. I get them fresh water 2x day with a 1/4 teaspoon of Vita-Pak* (contains niacin, vitamins, and minerals) mixed in per gallon. I am hoping that it is just a part of the growing phase. She doesn't get picked on that I can see at all. The 'pen' is a kids swimming pool with towels spread out on the floor. Anyone have any ideas or thoughts? * By Agrilabs Vitamins & Electrolytes "Plus" - It is what the hatchery offered Edited to show what the Vita-pak was.
