Currently I am feeding flock raiser to my ducks, chickens (laying and growing) and guineas. Once everyone is of laying age can I switch back to the cheaper locally ground layer mash? I know layena pellets are okay, so i think nutrition wise it may be okay. But ther is $5 difference in 50# bag, and that's a lot with my size flock. I am specifically worried about the texture of laying mash. Would ducks choke on the powder? I know I could make a crumble with water, but honestly, I don't have facilities to mix it especially when in a morning hurry before work. Also, I read somewhere where people were very passionate about too much calcium for drakes in layer feed. Is this true? Or can all mature ducks eat layer feed like mature roosters do? My local small town feed store folks already think I'm nuts as I am the only one who wants unmedicated chick starter and flock raiser. They typically have people doing "what has always worked" and i had to learn by the books and this website. I really try to research everything before I do it, as feed is expensive and I don't want to hurt my flock. My local feed store may think I'm crazy but I passed muster enough in this small town for them to ask me if I had extra eggs to sell, as a non-native to this area, I felt privileged. Odd how little acceptances mean so much, they are super nice people, I just don't want anyone to think they are anything but great to me from what I said above. Thanks for any input.
