The final part of the video that H2 shot, it shows how a chicken wanting to lay an egg approaches a full nesting box.
My eight Rhode Island Reds have been laying for 7 weeks now. I'm happy with the number and size of their eggs; I'd also encourage anyone thinking about raising backyard chickens to seriously consider the breed. They've been a wonder, at times, to behold. I'm just trying to get a handle on the ba-gawking.
