Its great to have an opinion on a subject but first it is important to see what the research indicates: 1980, Reece & Lott (USDA – Mississippi State) 3,000 ppm, 6,000 ppm, 12,000 ppm from 0 – 28 days 3,000 ppm, 6,000 ppm no effect on body weights 12,000 ppm depressed body weights at 28 days 2008, Olanrewaja, Dozier, Purswell, Branton, Miles, Lott, and Thaxton 3,000 ppm, 6,000 ppm, 9,000 ppm fr ...

CO2 is important, but remember the temperature. I have seen several examples of inactive chicks caused by low temperature. Depending on the conditions you should start your chicks at 33-35 degrees C. If air temperature is too low, the chicks will stay inactive to save energy and try to maintain body temperature. For sure a low CO2 is important, but I do not think that levels at 3.000-4.000 will m ...
