I think I know what is going on in the picture. Some bit of details are needed to explain how to build the brooder but there are none here
The build needs a different type of light bulb for heat source. cfl bulbs are toxic if they break A thermostat is needed too
Missed a bit on feather length sexing. That should go under the sex liknked section since the fast feathering only works with crossing a fast feathering breed with a slow feathering breed with feathering being linked to a gender
