I currently have 6 EE girls and was thinking of trying some meat birds (6) this year. Before I go and build a whole new setup for the meaties, i was wondering if I ordered some hatching eggs, will one of my girls do all the hard work for me and raise them as her own? My current set up is a 4x8 coop, and a 10x20 fully enclosed run. I also have a 4x10 portable hoop run that is attached to a chicken hallway coming off of my big run. I move the portable run between 6 different spots in the hallway so the girls always have fresh grass in the summer.
