I received pullets via mail order. The Black Australorp only has a black stubble for a crown (hardly anything at all) and the Buff Orpington has a very small one and on the pinkish side. They seem to act fine. Is it because the are young? They were supposed to be between 15 and 22 weeks. I am feeding them laying pellets. Where I live there is no field for foraging, only pea rock, I plan on planting a sod patch for them. As you can see I am totally new to this. Any suggestions would be greatly appreciated.
