I have been putting my 5 and 6 week olds out during the day, temp has been in the mid to high 90's. However , now a cold front has come thru and day time temps are in the mid 60's. Is this temp safe for them ? They would be caged, not free roaming. Back in the shed at night. Last night it got down to 59, left them in the shed brooder box with a 100 watt light, temp in the brooder box was only about 79. But they did fine. But I'm worried about temp in the 60's out side and a breeze. They are not quite fully feathered. I hate leaving them in the brooder box during the day as they are getting too big for it. At night they seem to be fine, I turn out the light and not a sound from them. In the morning I turn on the lights in the shed and they jump up and start eating/drinking and then appear to be waiting for me to carry out to the outside box. they allow me to pick them up, no fussing and carry them to the outside box,,,they really seem to like it out there. In the evening they are the same, seem to like to be taken back to the indoor box, ready to sleep. I think they wear themselves out during the day in the outside box.
