I know I'm going to regret that title 5-6 weeks from now... lol Question further down, after some rambling (or back-ground story)
My 4-5 days old Coturnix Quail chicks are just SOO quiet! Disregarding the one who had (past tense - (s)he is feeling better now) problems raising its neck and whined about it whenever (s)he woke up, as well as when I turned on the lights yesterday and one of the water bowls were empty, I haven't heard any "loud" crying from them. I only hear faint happy chirps. Is it supposed to be this way?
So far they seem to have had a blast; my brooder had a spot that was way above 40C/104F (closer to 45C/113F?), and also spots that were under 35C/95F. The chicks were all over the brooder; "sun-bathing" in the hottest of the hot spots, roaming around eating, relaxing in the coolest spot etc (I haven't seen any panting). However, I had to alter the brooder somewhat and put the metal door for my dogs cage in front of the heat-bulb. Almost everything else remained unchanged, but the metal door made the temperature in the brooder go down several degrees C! I'm now struggling to get even close to 37.5C/99.5F in the hottest of the hot spots!, but they seem to be happy with it (no more all out sun-bathing though, but no piling up either and still relaxed sleeping in all weird positions and angles). However, I do need to cover the brooder (card-board box) almost completely, i.e not much light getting in the box. I don't like that (not only because it must be boring for them in the "dark", but also because they seem to believe it is nightish and hence less active than before).
I tried uncovering the brooder a bit, which put the hottest "hot spot" temperature at 33C/91.4F. I heard no sound/complaining, but later when I checked 6-7 of the 11 were piled up (in a corner, i.e not even in the hot spot
). So that made my worried. I have added another heat source for now (an old light-bulb), but I don't want to use that during the night...). I will cover it up snugly (my wife did that last night - we weren't able to hit 37.5C/91.4F, but no piling during the night/in the morning as far as I could see). This leads me finally to my question;
Question
Will quail chicks (4-5 days old) be vocal if it is too cold, or will they rather pile up and crush eachother? (i.e can I rely on them crying/complaining about it being to cold, hence alerting me so that I can correct it before it is too late?)
