how long should my birds stay in the brooder before they can be taken off the lamp and put outside in their larger pen... I have bobwhites, chukars, and blue scaled quail... don't know if that makes a difference by species just though id add that in there.. I have been reducing the temp. in the brooder by 5 degrees every week as follows... 95 90 85 75 so they are at 75 by 4 weeks old/ any help would be appreciated. thanks.
