This is our first winter raising hens and are looking for a little guidance. We have four sex-link hens and two rhode island reds. Our coop has an small enclosed run attached to the hen house itself and is inside a 12x15x7 pen. It sits pretty much smack dab between our house, the back house apartment and 10 foot arborvitaes grow behind it giving it a decent amount of protection from the elements. OUR PLAN: Wrap 3mm plastic around the outside of the run to keep the wind out. Our hens already drink from a multi hen watering system that has a heating pad we will attached. Create a small den out of stacks of hay bales that can be covered with a trap to create more protection if needed. Heat lamp from when they were chicks. QUESTIONS: Do we need to also cover the small run attached to the bottle of our coop? How will we know if we need to use our heat lamp? If we want our hens to lay year round do we need a different type of lighting? Should we also buy a 300 foot thermometer to install inside the actual hen house so we can monitor the exact temp? Any help would be greatly appreciated!
