Dear BYCers. I have 12 laying hens (on laying pellets), 6 chicks (on starter feed), 3 young ducks (on grower duck feed). In my zeal to prepare for the birds, I bought huge bags of everything. I hadn't anticipated the fact that they don't know the difference between duck feed and chicken feed, or starter feed and laying pellets. It's all food to them. But I want to be sure they are ALL getting proper nutrition for their ages, and that the hens continue laying.Is it possible to combine all these bags? Is there something I could add to the feed so that it's universally appropriate? All advice is welcome. Thank you in advance!
