I have posted before about 4 weeks ago when I got my first chickens. they came from a local farm and the 4 chickens we brought home were between 4 weeks and 7 months or so we believe. One bird we cannot tell if it is a boy or not. I believe I am seeing something in the feathers and want to know for sure as the farm said we could bring it back for a hen. The last time I posted it was 50/50 on sex so 4 weeks later, lets try again. Dont know actual age of bird, but it is a large bird and I would guess around 4-5 months of age. The first pic is from 4 weeks ago, the rest today.
