I think the idea that chickens will 'pick out the best bits first' is another example of oft-quoted-on-BYC nonsense, at least when applied to real recognizable food and not some ultra-processed slop.eating first, he's getting the best bits I assume.
They pick out first what their appetites tell them they most need. If there's not enough for birds lower in the pecking order to get any of X, then there's not enough X in the feed for everybody's needs and the keeper should increase the amount of X until everyone gets as much of it as they want to satisfy their nutritional needs.
Have you been able to source that in appropriately sized bags for your needs?It doesn't really matter with regard to the nutrition because Spelt at 17% protein (and it's a complete protein) is the bulk of the feed.
Add a spoonful of plain natural yogurt and bingo - you'll have them too!I've got everything in that feed apart from live creatures.

They are a novel food for him. Was it obvious (in hindsight)?Mow and Sylph like prawns so I took them some, maybe 4 whole prawns each.
. It might be quite boozy this year, with the fruit pre-soaked in Baileys, and 4 tablespoons of spicy cherry rum in the mix too
