My LFS (local feed store) tried to get me to buy electrolytes and said the chick/chickens need it everyday! And said there was no difference between red and white light. For my second brood I changed to red light after a couple weeks and saw an IMMEDIATE difference in their behavior. They were much more relaxed instantly. But I keep learning and mamma heating pad is the next step. So, some of them are good, but I will always do my own research just in case. Some of them don't have a clue and probably never raised animals.
