I had a "crazy chicken lady moment..... I already had 12 chicks that were well assimilated 6 RIR and 6 Comets and the "man" said, "We don't know what these are, you can have them for a $1 a piece!" I told him I would take 6 and the rest is history. At least five of the straight run RIRs are roos so....I may be glad, I got these.....the Comets are supposed to be all pullets...we'll see! BTW most of my efforts to work through assimilating these new chicks in with the RIRs has been a failure. We had to buy a separate pen and the one dollar chicks turned into 350 dollar chicks! One of the roos is so bad he stalks and terrorizes them....he is going to a better place soon and has to stay in the run while everyone else is out.
