So I moved my 2 week and a half old chicks in our sunny room and we are enjoying lower temperatures this week (we're in Arizona). They had lots of fun today running around, digging, eating and exploring. They have been a bit scared at times by new noises and have decided to make a corner their "safety spot." Problem is, this corner is opposite to the where their ceramic reptile heater is and I am afraid that once it gets dark, they won't move to the heater if it gets cold (should go down to 50's tonight outside, but in the sunny room, hopefully should not get lower than 70) I tried feeding them under the heater so they could detect the heat, but they seemed to care less. They keep on going to the opposite corner to sleep. They are not piling up, actually some are sleeping a bit apart, but I worry in the middle of the night if they get too cold when temperatures drop. If it gets too cold, will they think about seeking the heat, or since it's dark they will just bunch up together in the corner? How can I let them know where the heat is, other than feeding them under it? thanks in advance!
