I got some pullets, ages 9 wks and 13 wks. Someone told me their 9wk old pullets were about the size of my 13wk-olds. But, they do have all their feathers. I figured maybe they were just crowded or something and were a bit smaller than normal. What do you folks think? The 13 wks olds are SL Wyandotte and RIR; the 9 wks are Australorp and a tiny buff Orpington. Photo with the kiddos for size reference of the babies.
