Hi, i have 1 hen that has been laying for about 3 weeks now, she allways lays in the same place, but not in the coop, now my other hens i think are starting to lay and i've been finding them in different places. How do i get them to lay in the coop? I put a golf ball in the nest, but it didn't do anygood, and also, my chickens are free range and we live in northern indiana, it gets pretty cold here, do i keep them locked up all winter? What is the coldest temperature they can handle? Thanks for all the help. I'm also having problems putting pictures on my page, can somebody help please and thank you.
