I ordered a box of sorghum grain to pop for myself. It didn't work out nearly as well as popping corn. Since we had a box of sorghum grain that we were not going to eat, my husband started feeding it to our three chickens. They are 3 1/2 months old. Now they follow him anytime that he is in the yard. I have tried meal worms, fresh vegetables, fruit, and oats as treats. They are O.K. with oats, but ignore anything else except for the sorghum. They will do almost anything for the sorghum. I have set the limit at 2 TBS sorghum per bird per day. Is this too much? just right? or can they have more, then how much?
