Today, I let my 2 pullets (flock) out to free range. I noticed that they were not glued at the hip as usual. My RIW kept wandering off, into junipers, other bushes as if trying to nest. I put her in the small coop into a nestbox....she stayed for maybe 30 seconds. Hubby was working on our coop (a reformed doghouse) to put in a low wattage heatlamp. She did NOT do any eggsong, was vocalizing totally different, not like begging for food, but more of a high pitched whine....anyway, hubby thought I should lock them in the coop for awhile. I did that. There was no loud squawking or anything. Went back maybe 15 minutes later and let them go out into their run. Because their woodshavings were all over, pushed them back where they belonged. Lo and behold....there was a warm egg! Perfect, not a soft shell Observe the birds...I was SO excited!
