We have been working on the coop for 4 weekends straight.. should be completed this week.. Darn rain has really kept us going slow! anywho.. we hope they will be in the coop today.. so we just turned off the heat lamp in their brooder.. Do you have to get them used to no heat lamp for a bit.. before sticking them in the coop and really dark over night? will the darkness freak them out? Our lows over night will be in the 40's and 50's.. the coop is insulated but we do have ventilation in the roof.. Maybe only put on the lamp over night for a bit? thoughts? thanks!
