The shelf setup and the nest box split down the middle seems to be the most productive system. Dual shelves work well also. My birds will lay eggs on one side and when the babies are a certain size, they move to the next side and lay another round.
Hi Can you please do a video of maintaining a line of bird and improving quality over time... Reason I am asking is I know you have these over 5..7 years and you know your current birds pedigree..Thanks in advance
