We bought 4 Cornish X from TSC Sunday the 18th. A woman who worked there said they had the chicks there for about a week and they usually receive the chicks a couple days after they hatch. By our estimate they should be around 2 weeks by now. I'm reading about how CX grow so fast and now second guessing if we actually purchased CX. The CX are supposed to be the one on the top right and another at the bottom. We aren't sure what the yellow left top one is either as it came from a different bin with no specific breed label. So my question is if they are CX are they growing on track? Or are they not CX at all?
