Hi! My chickens are now 4 weeks old, and I know it's a bit early to move them outside, but the weather has been nice lately and they have grown out of their brooder and they have been outside at daytime the last 5 days, and they just love being outside. I have the Eglu Cube coop from Omlet, and I installed a brooder heat plate inside of the coop since they are only 4 weeks old and also used sawdust inside the coop instead of the rooster bars because their feet are too small for the rooster bars I think. They seemed to settle inside as long as the door was open so they got daylight inside the coop, and it was nice and warm in the coop, but when I closed the door for the night they got extremely stressed and I just had to take them back inside the house for the night because they didn't stop chirping. The thing is that I live in the arctic and we have midnight sun, so they aren't used to darkness at night in their brooder. What should I do?
It might actually be too warm in there?
With the sun up all day, and then it being a small coop... it will hold in the heat.
Also... with it being so small, they can't move from a warm spot to a cold spot.
Is it located in a perfectly secure run?
If yes... then I would leave the Eglu door open.
But watch them and see if they are smart enough to get in and out of the Eglu whenever they want.
I sometimes have chicks that are royally dense... and I have to show them several times how to get from coop to run... in my elevated coop chicken tractor.
The first year with chicks in the far north... they do NOT have any idea what to do with all the summer light.
My old ladies, or chicks raised by a hen, go to bed at a decent-ish time, even with the sun up all day.
But don't worry, those chicks will be fine next year with the daylight swings.... just not this year.
As to space in a coop... I highly recommend 9 square feet per bird of roofed and sheltered space. I manage that much space by giving my large flock access to the greenhouse in the winter. Just with long dark winters, especially with gobs of wind and snow, they either can't or won't go outside much... and then, if they are in a small space, will start to eat each other.
Can you wire in your terrace? And is it roofed? Make the entire thing a chicken run? With a thick tarp on the floor, then hay and/or wood chips, might work fine for winter.
I hear you on the snow.... I have an article with pictures of my coops and some cold weather tips
