I think I got "Tractor Supplied" by not having my Storey's book. This has too much protein, doesn't it? I'll have 4 ducklings and 2 goslings in 4 weeks. I was already planning on niacin through peas and brewer's yeast, plus meal worms, but can someone direct me to a better crumble for 2 day olds through (2 weeks? 4 weeks?). I've reread the book several times and am suddenly feeling lost on feed until fully feathered. I'll be adding greens and grass. I'm not sure what feed to buy, protein differences between the two, when to switch off crumbles, adding oats, etc. I think my nerves are getting to me! Chewy and Farm & Fleet are easy options in addition to Tractor Supply and Amazon. Thanks in advance!
