I was wondering how many people use vitamins and electrolytes when their chicks hatch. Do you use them? For how long do you use them? And, why do you use them? Also, what brand do you use? I use Durvet brand, because that it what my feedstores have. So its really easy to get. I always like to use them for at least a week after hatching, or if the chicks are mailed to me. Usually its more like 3-5 weeks. I always use them on my bantam chicks, like Silkies, and Sebrights. I find that it helps them adjust better going from yolk to chick feed. I also like to use it on my call ducks when they hatch, but only if they are hatched in an incubator, not if the mother hatches them.
