I have 12 large-breed chicks of varying ages and just aquired 2 Broadbreasted Bronze turkey chicks. My next door neighbor has about 5 of these huge birds and they just have them in a lean-to structure in a dog kennel run. What sort of housing will I need for my 2? I'm assuming I won't be able to house them with the chickens as they get big, but can they share the same pen while smaller? Also, they are straight run, how will I be able to tell the sex and by about what age?
