As tiny as those chicken brains are sometimes we can't figure out what is going on in that pea-sized organ. When chicken decide they no longer like the coop you have to figure out why. Is the roost too low.?Is the place to small allow for the natural pecking order to take place? Too hot and stuffy? Is there a predator bothering them? Could be something as simple as a wasp nest, trolling cat or as serious as raccoon, opossum, or nosy dog disrupting the girls from their rest.
Once chickens decide to roost elsewhere, you have to either make the new place disagreeable to them, remove it, or keep the flock away from the area. The decision is yours. Some people are ok with losing a few here or there to predators while some folks want to keep their hens away from harm.
My flock stays secured due to the number of predators I have, and if I do let them out it is near dusk so they don't wander far and I have to watch over them. I have hawks, owls, foxes, raccoons, opossums and a horse who thinks chickens make great targets for his hooves.
So the girls stay in the run and I bring nature to them. I bring various plants, and occasionally supplement their diet with meats and other strange items to give them variety and to give me funny photos to share with this group.
My advice is if you can't tolerate losing them, then get building. Make the chicken area as chicken friendly as possible and as predator proof as possible. Give them as much room as you can afford as you may eventually add to your flock.
Good luck and keep those girls safe!Hello, um, Oldchick? I have to get a coop soon,. my husband threw one together for them and while I appreciate the effort, its becoming apparent the kids didn't. I yesterday put the first of the free range hens in with them and this is the first night they stayed all in one place. The "coop" resembles an old fashioned outhouse, it just needs a door with a crescent moon on front and it would be complete, as an outhouse

As soon as i can afford it , i found some cheaper coops prefab on ebay that are in my price range so i will use the "outhouse/coop as a brooder i think. The hen likes it and is sleeping on the sawdust floor but I need to throw a perch in it. There is a nest box that the other hen used to perch on the side of at night before she reverted to the trees outside with her sister. No way no how am i ever going to be able to get through losing even one of my beloved birds. I know it will eventually happen but I would sleep outside on a chair with a shotgun before a predator would get them. We too have every predator known to the woods. Working hard to keep them safe. Their run is fenced in and covered on top with netting both to keep the kids in and hawks and neighbor tomcat out. Heres hoping, I am stiill a newbie
