Currently, I hand feed my 6 pullets/hens dough. Those dough were made of roughly 15% milk powder and 85% wheat powder and it's the main meal for them.
In the past few years, none of my chickens seemed to like layer pellets. Also two of my newest pullets had problem growing feathers when they were 8-9 weeks old, thus the milk wheat dough.
My pullets/hens are free ranging at least 8 hours every day, so they also eat plenty of grass and whatever worm/insects they can catch. On top of that, they are occasionally given prawn heads, meat scrap, green vegetables, seasoned fruits, rice and bread. So their diet is mostly corn/soy free.
They pullets/hens are very healthy, they give me 4-5 eggs every day amongst 6 of them and their eggs are delicious.
