My week old chicks are on medicated chick starter. I was given some not sure how old it was but the chicks don't like it as much as the stuff I bought and they waste so much there is more than a few cups on the floor the brooder and they do have a proper chick feeder they seem to scratch of the bigger pieces. If that makes sense any ideas what to do? I will go buy some more of the finer stuff I had before tomorrow and can I feed them other items? I do have a 4 week old bantam in there with them also she is the same size.
