20% is too low, IMO. 24%+ is preferred. ( I use 30%, they grow bigger in a shorter span, bigger birds will lay bigger eggs.)
Also, if they run out of water, even if for a short time, they will stop lay almost immediately. I have a gallon waterer and have had to fill it up twice a day before...
I would compare them to a wild birds call...
Noone will even know that you have them...
Also not classified as poultry ,as a side note, can most times have them without restriction.
This is only Production Red chicken eggs but I made a guard for the old style turners that don't have a shield on the motor. That spot closest to the motor can actually overheat that egg. The motor gives off additional heat but it might not be as much of a problem in a forced air...
It's only...
I have done this in the past when I didn't have quail rails and not enough space to fit all eggs in the universal rails..
Cut down water bottles taped to the rails
I would only do it in a forced air
