These hatched mid nov 2013. Have never weighed them but id guess there around 2 2.5lbs now. Prolly cock out somewere in 3-3.5lbs range. there a little taller than my full grown ko shamos now at 4.5months. Have an extra stag maybe a pullet not sure if im gonna keep her just yet. Linege idk. Picked up a smaller shamo pair a few yrs back and keep the smallest looking late hatch ones.
