I feed a 24% GameBird starter, with meat protein. I feed this until laying commences. I have also found a high quality, 18% Layer, with meat protein. Once the birds are old enough, I also supplement with table scraps, garden produce scraps and a bit of tossed grains, a simple 5 grain mix. I'm also using Calf Manna this year.
Some of my co-operative partners have dairy cows and have access to whey, a great supplement.
The plastic spiral type legs bands I have found locally are not what I want to use, so I've passed on them. We'll have to order some more, which isn't an issue. There are many online sources. Meanwhile, vet wrap strips are fine for temporary use.
