Hello All! I have only just found and joined this forum, and am looking forward to sharing tips and advice! I have 17 ducklings, which vary from about 4 weeks old to about two weeks old. We made them a predator-proof pen from a stall in our barn, and they have been happily living with our five chicks. I have been feeding them chick starter, and the always have plenty of water. Unfortunately, ducklings being what they are, it never stays clean for more than a few minutes... Over the past two or three days, I have noticed a few ducklings seem to have trouble lifting their bodyweight and walking properly. They kinda spraddle, bow-legged, and scoot along. Three were pretty bad, and all the rest look just a tad bow-legged. Their legs are looking strong and in proportion to their size. This morn, I found one of them dead. I think it was one of the worse limpers. I have been reading about Niacin deficiency - is this likely to be what I am dealing with? If so, what should I ask for at the feed store? A supplement to go in their water? Plus, I have Goat B12/Thiamine (well, cattle) on hand - can I squirt that in their drinking water? I am located in NW Arkansas, if region makes any difference. Thanks!
