We are getting a large straight run order in soon and are getting ready! 51 chicks!!! We're getting dual purpose breeds...Buckeyes, Delawares, Salmon Favorelles, Jersey Black Giants and Mottled Javas. The posts I found on here usually referred to meaties and Cornish Xs. What age should be cull our roos? I know they won't be as meaty as "meat" birds, but I don't want a tough bird or a crower...what's a good compromise?
