I'm not sure where you heard that, but chickens can most certainly see daylight. Also, unlike dogs, chickens can see a wide variety of colors. However, most chickens have quite bad night-vision.
weasel
They can see in dayligh, it is just that they fly at night because the suns not out, so it doesnt pucture there wings, and there is less predators and competition. HOWEVER some flying foxes fly in plain daylight.
no, you do not have to heat your chickens coop. all you have to do if extend your chickens daylight hours. i usually have my lights timed to come on at 7am and then turn off at 8pm.
They don't. Some hens will lay at night, some in the daytime.
penguins cant fly, and chickens cant propperly fly!
Q: if a chicken says "All chickens are liars" is he telling the truth A: chickens cant talk
Yes put the chickens inside an enclosed area that the hawk cant penetrate.
If the garage has no light (windows) then i wouldn't keep them in there that long. Maybe a few days as chickens need sunlight to lay eggs, and if you have a car in the garage then i wouldn't keep them in there at all. Chickens would prefer fresh air and some daylight so its not an ideal place to keep them, they also like wandering around the garden finding worms and insects. The garage cant give them this.
they cant stand daylight or garlic
Yes they can, they can see perfectly well in daylight. But they prefer to hunt at night, not during the day time.
eat them
You can...
