We rent. The property has three acres, a two sided 'coop', place for a garden, even a pond off the finger of the bayou that comes up behind the house. The coop is basically a metal shed with a fully fenced front so we can leave the outer metal doors open at night during the summer. (NW Florida gets very hot, even at night.) Anyway, there's a light fixture on a beam in the center of the shed. This particular hen roosts on that beam, just above the light switch/bulb. It's never mattered if it was just at dusk or full dark, but she's always squawked at me when I turned out the light. In the mornings I find the pull string twisted up around the beam like she's been trying to turn it back on.
Sadly, they go through about a lightbulb every two weeks. The chickens don't break the bulb, but I think they shake it enough to break the filament inside. I don't want to put any of the curly bulbs in there just in case they DO break a bulb. Those things are just nasty to clean up and would probably poison the chickens.
The last few night the hen has avoided going into the coop at all, unless we catch her and put her in. I can't leave her out because there are foxes in the area and we lost a hen in the last couple weeks who stayed out too late and I couldn't find her to put her in the coop.
I don't know what to do. I've read that keeping a light on all the time stresses them, but this hen just seems to hate the dark.
