I purchased 7 buff orps and 3 plymouth barred rocks, and Ideal sent me 6 extra chicks to keep them warm, I have no idea what sex or what breed they are, but they are yellow, they said that they sent extra for space in the box and wartm and that they are "236 Ideal Males", what in the world does that mean?? not sure what to do with them, I wanted all GIRLS..they are very cute now.. they are all 1 week old today.
