Curious if anyone has ever done any light therapy to ehlp encourage chicks to pip or hatch? Since my son is a science major he asked if light effected their hatching timeline like humidity and temp do. I told him I didnt know but we would run a few tests to see if it makes a difference. I have noticed they rock away when the light is shown on them. So I think one egg who is a rockin away will have some light therapy as well. on for 10 off for 30-45 then on again with no extra light at night when everyone is sleeping.
