I've got a gentlemen coming to pick up these pullets and when I said one may be laying, he said 'Oh you can't tell just by handling one? I can. Tsk tsk.' She may or may not be a new layer. Her comb is 'getting' redder, but it's not fully developed. The roos are mating her, but seriously, can you tell just from holding a pullet if it lays eggs or not?
