I apologize if this should be posted under another thread. I'm a newbie, so please forgive. I have three chickens - two RIRs and a Brahma/Cochin mix.The RIRs are about 23 weeks. Their combs and wattles are getting red, and one has been squatting when I reach down to pet her. This morning, when I let the girls out of their coop, Rose (one of the RIRs) was wandering off from the other two (which none of them EVER do). She was kind of pacing around the yard and acting differently. I went out later to check on them and couldn't find her. I was panicked, but then looked in the coop to find her in the nesting box. She was laying there very quite and still for quite some time (a couple of hours). I thought for sure I'd get an egg today. However, after going out a couple of hours later, I found her out of the coop and - no egg. She had clearly been trying to make a nice nest to lay in as the shavings were moved around and a nice nest was formed. My question is this - is this typical behavior? Do some hens go in and out of the nesting box - spending long periods of time in there before they actually lay? I sincerely appreciate any opinions that you can share. I can't contain the excitement, and the suspense is killing me!! Thanks so much!
