I have 14 blue laced wyandottes coming my way tomorrow, about a week old. This is my second flock yay! I went to the feed store and they didn't have chick starter, but they said the 18% protein layer feed would work just fine. I am not medicating my chicks, didn't medicate on my first flock and they were all fine. Is the 18% layer feed fine to feed week old chicks? I am a bit wary!
