Since I'm very new to this I need a lot of advice. My chicks are due to ship 3/20 (expect them on the 21st?). The minimum order was 15 chicks so I picked 5 BSL roos and 10 GSL pullets. Is this too many roos? Will I need to order more pullets? My thinking was that (Lord forbid) I might lose a few the first few days, and I wanted to make sure I had a decent mix. Was my thinking correct?
