Actually, to show any birds, they should be in Mature and best plumage. Pullets may or may not have started layng, mine usually start at about 4-4 1/2 months. But they are not hens until a year old, laying or not. Keep track of their age, even if maybe not exact. If you plan to show, you will have to take extra care of their plumage--keep feathered feet and legs from wear and tear. Keeping them clean, will make their prep (bath) for Show, easier. It is great pleasure and you get to meet others with like interests--really nice! Lots of good keen work! Good luck, Woodenshoes....
