We have a broody hen with eggs in a high horse feeder. I think she is fairly safe there, but I don't see how this arrangement will work once the eggs hatch (if they do). It is starting to get cold at night. The next two months will be a tough one on chicks. The current plan is to wait and see if any chicks hatch. If some do, we would move mom and chicks to a pen or dog crate. Does that sound reasonable? We don't have any experience with hatching chicks. We have always ordered chicks and raised them under a heat lamp. This spring, an order had a bunch of roosters included for warmers. One of them is still with us, so hatching our own chicks is suddenly possible.
