I have 5 Pullets - 4 Doms and 1 RIR, each of which are akmost 3 months old. I was reading on the Chick Starter bag that it should be the sole diet for the birds. Is this true? I have been giving them treats from time to time and was wondering if I should stop doing this or if it is alright to continue to give them treats sporadically during the week. Thanks for the replies.
