There is that one chick in a hundred or five hundred that simply doesn't quite fit the typology. Suddenly, at 14 or 15 weeks, they FINALLY show themselves. It is very rare. Very rare. But it does happen. I wouldn't worry about it.
Thank you; my brain was tired and slow last night and for some reason I read it as "some of your pullets look a bit "off" " So I was trying to figure out if there was something wrong with them! It all makes sense this morning. At least it's Friday!! Thanks again
