Okay. Petrie has two big bumps on her legs (little spurs), now she's getting two smaller ones just slightly above. Here's a pic I drew in paint:All pullets and cockerels have the tiny bumps on their legs, of all breeds. Not sure what you mean by four of them-would have to see a picture of that, but cockerels don't even get spurs until they are well over 7-8 months of age.
