Hello Guys! This is my first post on here so go easy on me please!! I have recently started keeping chickens, I have 3 in total. 1 Amber, 1 Light Sussex and a Goldline. They have turned 20 weeks old a few days ago and I know that they're getting closer to laying, the Goldline in the past couple of days has started sitting down and not moving a lot and occasionally falling over as if she is bottom heavy. However when food is put in front of her she will run for it and is quite happy to run away when someone enters the coop! I have found her on a couple of occasions sitting in the nesting boxes but no eggs. I would just like someone to help me and clarify my suspicions, is this normal and because she is getting closer to laying? I have attached a photo to hopefully help explain it a little better. Thanks in advance.
