All but one of our chicks survived and then our neighbor gave us 4 hens so we need to thin the flock a tad. I prefer to take out any roosters first. I'm new to this though and I need alittle help. I've numbered them. Please let me know if you have any opinions on the sex. 1) I assume this is a white leghorn. Purchased from a feed store March 10th so approx 11 wks old. 2) I assume this is also a white leghorn. Purchased from a feed store March 10th so approx 11 wks old. 3) Supposedly an Americana. Purchased at a feed store March 15 so approx. 10 wks old. Thanks for any feedback!!
