I hope this doesn't sound to goofy this is mine and my girls first winter together. I have most of them laying, of the seven. and I try to make sure as much as I can that they'll keep laying and be happy and healthy birds this winter. I was looking for advise on an additive or additives to my curtain mix. Or a new mix or a custom blend ? We were already thinking of adding flax seed, as well as any others that would make for happier healthier birds. I know my hounds and cats eat differently in the winter so I thought it only made since, to bust their diet.
