That may be the cheapest way to go about it. The protein in the vegetable sourced feeds is supplemented by synthetic lysine and methionine that you'll find posted in the ingredient list. They are down the list near the added stabilized vitamins.
Just look for the crude protein % and look for meat/fish to be the first ingredients listed.
I opt for plain meat or fish. I have 60% fishmeal that I mix in at a 10:1 ratio that raises a 16% feed to 20%.
A really cheap and simple thing is canned mackerel. Good quality fish and the cheapest canned one can buy per ounce in a grocery store.
That's fast and convenient.
The first time I raised a big batch of meat birds as an adult, the only place I could find was about 60 miles away in Illinois. Add the travel time/cost and price to the cost of raising them I decided it didn't make sense not to do it myself here.
Nice. Is that an Arduino Uno?
I'm working on the same thing.
Mind sharing what sensors you/he are using?
You wake up little Suzie, it's too cold here.
The weather man says it is +3 here but I'm measuring exactly 0 F here at 5 AM on my Thermoworks instant read.
I'll check it closer to sunrise.
