New chicken mom here! Obsessed with temperatures! I have 4 thermometers and I trust none of them! So the first week I tinkered with the height of the heat lamp, and found they were happiest about 92-93 degrees. Now it's the second week, and the chicken books are in my head, saying "drop the temp 5 degrees." So I raised the heat lamp, and the temp is now in the upper 80's. Two are huddled under the lamp. Two are on the opposite side of the brooder. How the heck are you supposed to know what's the right temp? I need a tranquilizer. Or at least a glass of wine.
