I was mailed 12 Maran eggs for my broody Orpington. I was going to leave her in the coop nesting box but after reading here it was not recommended I am setting up a separate area using an igloo dog house and a medium wire dog cage for the run. I am just north of Washington DC. Here are some of my concerns: 1) Will it get too hot in the igloo? It has a vent in the top. 2) I will not be able to see well into the igloo. Will, it disturb her too much to lift the top off once in a while to check her? 3) Will she stop sitting before they are finished? She has been sitting on a marble egg for over a month.
