Daffers is 'on point' there
I also feed Smallholder pellets, I do occasionally add the following, just because I have it around: seaweed, cod liver oil, biotin. I occasionally get a bag of Dr Green's Co***** Layers Mash, which they really love. I feel that it's a bit rich though, so cut it in with the pellets. It's especially good at this time of year when they need extra support to re-feather and gain extra condition for the winter.
Mine won't touch anything by Dodson & Horrell - they're not remotely fussy eaters, just consistently turn their beaks up at it.
I also don't feed corn, but a mix from the local feed store of their duck and goose feed, with their poultry tonic seed mix - not fattening, but sufficiently tasty to get the little cluckers interested
