I have 4 silkies and they are all 7months old. 1 started laying at around 4-5 months and the other 3 has no signs at all. One of them I can see waddle and comb so I was thinking that he is a roo. But today when I was playing with them and chase after them, I saw him squatting when I walk close. Could this mean he is a hen? All of them hasnt crow or anything yet. But right now I am sure that I have a silke hen but she gone broody so she hasn't laid recently.
