Hi, looking for some hactching eggs for my 12yr old as a 4H project, he just got an incubator for his birthday and is excited to try it out! Currently have large birds only and looking to keep it that way, have some barred rocks now and love them and have wanted orrpintons for awhile, seems your post might be a good fit? I believe his incubator holds 40+ eggs, but we dont want that many!! What do you think would be a good number to start with?
