Whilst my hens have access to proprietary feed all day (they "free range" in my half acre garden) i like to give them something extra every day as a treat. I have been feeding them a thick maize meal porridge (imagine stiff polenta) and saw some gram (chick pea) flour on the shelf, so i mixed in some of that. It was a bit of an epiphany and used up some of the gram flour that i have had for way too long.
For those of us in Africa (i know there are some South African members) this maize meal porridge is a staple diet in many countries (and goes by as many names!) but just thought that sharing this idea may be useful, as feeding chickens this porridge is very common.
