I buy 4 bags of Layer pellets (mill brand) at 8.90 a bag I buy whole oats at 14.95 a bag either 2 of these or a alfalfa/oat pellet ( use in winter for horses) if need be. I buy 25 lbs of calf manna (26$ and a large bag of TS cat food and I mix the layer, oats, calf manna and cat food (only handfulls of these as they are concentrated and high in protein) .The calf manna last 2 or more months. so I figure around 55-70$ a month and I have 11 geese,11 adult runners, 9 large saxony, 9 Dutch Hookbills,9 mini ducks right now, and 19 baby ducks. Oh, and I am buying starter for the babies at 8.99 and I cut i with oats for the young geese to get 16% feed.
Only time I saw Mazuri here it was 75$ a bag at tractor supply. One bag. I also have tons of free flies as I live next to farms,a nd any that are near the ducks get eaten, they also free range for bus and greens in fenced pasture in daytime.
As far as being worrying about them not coming it. Ducks and geese train easily. Feed at a regular time, (evening only if you want them to come in), start when they are under brooder(if babies , whenever I fill feeder and give greens) or in pen if older and say " Dinnertime" or any word, "cookies" etc. Use a whistle, anyway. It's "Operate Conditioning" like Pavlov's dog experiment> Pretty soon ,if you say "dinnertime" and have a bucket (I try to use the same color bucket), they come running, put the food in the house , retreat if necessary, and raise arms a bit and shew them in, close door, next day let out.Repeat.
This will morf into'whenever you are out working or walking , everyone gets under foot....
