I have a silky that is broody again. I would like to hatch a few marans eggs, but DH says it is getting too cold and I should wait till spring. I want more eggs in spring!! When is it too late in Ohio? She is in a coop with a few other chicks that are 3 mths. old and a silky roo. I am planning on getting rid of my extra roos and moving my pullets in with the other girls soon, before the babies would be born. Would the momma be able to keep them warm enough with out a heat lamp with our coming colder weather?
