Hello, Well my 4 week old chickies are progressing very well but when my husband went to buy more food the other day he came back with a different kind than I had gotten the first time. I was worried about the difference but there was even more than I had thought. It turns out the first bag I got was medicated. The second bag is not. I just started using it this morning. He has gone out of town. So now I am solely responsible and my chicks are vulnerable. I had not intended on giving them medicated feed at all, but that could be the reason they have done so well. Do you think we are going to have problems with the unmedicated feed or should I go looking for some that is medicated. Thanks for all your help.
