Heat lamp or not? New to Ducks!

[yarnchick]

I put my first batch of duckling in tub around 1 week. Just for a few minutes. Then dried with towel then hair dryer. I just received another batch of duckling yesterday. They are now 4 days old. This time I got Blue Indian Runner hens. They seem to be doing very well. Took them outside in sun and on grass for about 5 min. They loved it. The bigger runners just looked. I want to try this every day as long as the weather is warm. Hope it will make my job easier when it comes time to put them together. I know you will enjoy your new babies. I have mine in a plastic tub in my yarn shoppe. Everyone has to have a look see.
