hello... just got 6 of 9 chickens to come out of their coop for the first time... they're three weeks old. I have this grain cereal that I don't like: it has cracked wheat, cracked rye and flax seed.... is that ok to give the chicks to scratch out on the ground? thanks (I really don't like it... it tastes like bird seed to me so I thought they might like it.. and I'd not like to waste it if they'll eat it).
