I have a wonderful laying hen named Rita. Rita & her coop mate was attacked by dogs & the mate was killed & Rita injured. For 2 days I cleaned & medicated her wounds and believe it or not she kept laying eggs. 3 days after the attack a friend (to ease my sorrow) gave my three teen hens. I was delighted!! Rita seemed so happy too as she treated them like a new mom w/babies. Buttttt she stopped laying. Thats not a problem for me because I figured as she got use to the new ones things would get back to normal. The thing is I can't get the teens to go into the hen house at night. They roost in the bush thats in the chicken coop. It's getting cold at night so I want them inside the hen house. What should I do????
