These chicks are just random mixed breed chicks I gave a broody sebright/silkie cross to hatch. We won't have meaties until later in April...
I would say use it if you have to but if it were me I would only use it until I got to the store to get the regular starter. Usually the lower the protien the cheaper the feed. Save the other stuff for your meaties when they come. The higher protien won't be a problem for a week or so. At east I never had a problem, and I have raised some silkies this way.
