Thank you for all the support and advice. The two that didn't make it never ate food. We dunked their heads in their water (with electrolytes and a touch of ACV) and at the end were using medicine droppers. I think part of the problem is that their legs weren't strong enough to get them to food and water on their own. I tried for a day to get them to eat food, but they refused it over and over. I tried corn water, sugar water, electrolytes, probiotics, vitamins, regular dry chick feed, FF...but they still didn't make it. The healthy 3 chicks drank from the start and started eating the second day. All I had to do was peck at their food with my finger and they were all over it.
I'm using non medicated feed and I use FF for the larger birds, so I figured I might as well get the chicks started on it now. They're eating great! Digestive tracks are working well
Ok, I'll take out the rocks...and I guess they don't need the drawer liner anymore either, huh? Thanks again everybody!
