My chicks are a little over 2 weeks old. I have been keeping them in Rubbermaid tub for a brooder but they are getting big and crowded. After the biggest one jumped out this morning I am considering moving them to our coop maybe with a heat source like a heating pad? My coop is 5x7. We have a heating lamp but thinking a heating pad might be safer? We do not have electricity in the coop but it is close enough I can run an extension cord temporarily. The temps here in Mo lows in 50's at night and mid 70's during day. Any thoughts/opinions would be appreciated. TIA!
