I have 7 Bantams, 5 of which are Silkies, and one Cochin and a Mille Fleur D'Uccle. They are just over 8 weeks old now, and I've tried several times to give them treats and they just aren't interested. I'll throw them various tidbits, produce, noodles, etc., and they run over to it as though it's appealing, then peck at it once and walk away. They don't eat any of it, with the exception of scratch which they love. Is this odd? Has this happened to anyone else? Is there something in particular I should try or should I just not give them treats if they aren't interested?
