Basically, I had a couple of spare calf buckets (I have an obsession with buckets) so I put a couple of scoops of mixed poultry corn in one, standard layer's mash in the other and filled them up with tap water. I gave them a good stir about 5 times that day. The following day the water was cloudy so I gave it a stir whenever I walked past and by the fourth day the corn and mash buckets looked cloudy and foamy respectively. Both smelt vaguely sweet and sour which is the classic lactic acid bacteria aroma so I felt confident that the buckets were preserving the contents well.
Using a plastic sieve for each feed, I use a portion of the mash in the morning, mixed with dry layer's mash to form a crumble, and in the afternoon I feed a portion of the fermented mixed corn again, mixed with a bit of dry mash to soak up the excess liquid:
Mmmmm (if you're poultry)
Well, the hens go mad for it! They are tucking in really well in the morning and afternoon and are rather snooty about eating the pellets which I give them in between times for ease and in case someone else needs to feed them (should I do something radical like go out for the day) so I've been really pleased. I top up the buckets with corn or mash and water and the mixture perpetuates itself. As long as there's always a layer of liquid over the feed it will not go off as the population of good bacteria keep the bad ones in check.
A word of warning: I discovered my dog rather likes the liquid so I have to keep the buckets covered with an old plate rather than the tea-towel I was originally using as he could push that out of the way and get his nose in.
I also feed it to the ducks and although they don't quite know how to handle mash as they dabble in their water bowl then back to the feed bowl and I end up with two bowls of slops...
The next thing I want to try now that the weather has warmed up is some sprouted greens as being on mulch the hens are reliant on their daily leg-stretch in the garden for some greenery.
