All of them, even hens sometimes... When do they get them? Depends, most are around 4-5 months but i've seen some that started about 6.. And if i remember correctly some that got them around 3.
Even hens can to!!!! ???? Now I am never going to figure out if i have roosters or hens!! So if I have this right, hens can get spurs and crow too???
I guess if a egg shows up then i will no for sure.LOL!!!
