my husband bought 2 RIR at feed store. The have chipmuch stripes. I went back next day to feed store and bought another RIR, it looks nothing like these first 2. Over the last few weeks the first 2 seem like they havent grown. They are tiny compared to all my other chicks the same age. At the feed store the bin that had similar chicks was labeled wellsummer bantam. What did we get?
