Wao I found something just like that. It was used for bread. I have it outside. I put screen on it so my seeds don't fall. So far it's working. I use the top empty to protect from other birds. My only concern is that the fodder roots might get stuck to the screen. I'll post how it works out.Just set up a fodder system big enough to supplement my horses' diet! I lined the trays with paper towel to hold the seeds in place until they start to mat. I am going to mist them to avoid ruining the floor underneath. I've been misting my chicken fodder trays and it seems much more effective than watering. I have a horse who has ruined his front teeth by cribbing and has trouble grazing so fodder may be a much needed boost for him.
