So....its me again. All the girls recovered nicely from their last bout of coccidiosis...and here I am, hemming and hawing over whether or not I should turn on the heat lamp. Right now it is 13 degrees out, but the deep cold is coming overnight. I have 18 girls in a 10 x 10 coop....just reassure me they will be fine. Because I know they will, with NO HEAT!
