My mid December hatch is growing. Of the 7 chicks it seems only 2 are pullets. The other 4 are all males- 2 sex link males (RIR x plymouth rock hen) and it seems 2 of the RIR are getting spurs. There is one mystery chick. So what is the normal age for spurs? At this point they're tiny little raised bumps. I was hoping for more pullets. Thankfully I have 6 in my incubator now that are due to hatch today.
