Hi everyone, I'm new to chickens, brand new in fact, I got my first two chickens yesterday I'm curious as to when's the best time to shut the door to the coop. My girls have been in and out all day but mostly in the run. I'm in Yorkshire, England and it's getting dark about 5pm at the moment. Should I be encouraging them in and closing the door, or letting them go in when they're ready? Thanks in advance.
