So, I'm going to try the Brinsea Ecoglow Safety 600 this time instead of a heat lamp with day-old chicks, who are coming home Friday. Can anyone recommend a good starting height for the brooder panel for standard breeds (Barred Rock, Australorp)? The instructions say, "As a guide, for bantam chicks start with one end at 1 1/2" and the other at 3." However, there is no mention of a starting height for standards. I've never raised bantams so I'm not sure how they compare as chicks in terms of size.
