The chickens have spent the spring and summer sleeping on top of the little dog house I purchased when there was only one chicken, Rosie. There are three Rhode Island Reds now, and when spring weather broke the winter spell we were all under, they stopped sleeping in their large and comfortable dog house and started sleeping on, and laying their eggs in, the smaller one.
After several nights of rather cold weather, I noticed they are once again sleeping in and laying their eggs in their larger quarters. They have closed down the 'summer cottage' and opened up the 'winter house'.
I am reading this move as the official Rosie indicator that summer is over. With the addition of the other two chickens Rosie no longer spends her winter nights in the house with us. I miss her companionship in the evenings but I am certain the cats do not. She didn't take any crap from them and got herself crated early on several evenings for slapping a cat around for no other reason than she felt like it. I miss you Rosie...I'll see you in a little while with your dinner. Its gonna be tasty.
