I've just finished breeding and the base of my softfood is very similar to yours. I can confirm that I have had a bumper year on it having reared 21 borders from 6 pairs, about 70 new colours from 10 pairs and 10 fifes from a single pair. I use Orlux, cous cous with olive oil and poppy seeds, into which I process about 5 slices of white bread, or garlic bread or even plain sponge cake. I add my vitamins and palm oil to the mixture and sprouts with peas and sweet corn (thawed) I have had zero wastage and my birds are looking awesome, despite being totally broken from the moult right now. Just thought is share. By the way I haven't used any eggs at all. I also offer all pairs with babies dry hand rearing formula free choice.
Merry Christmas and a Happy New Year to you all.
