Hi ! I have three chickens, and I think one might be a roo! Two of my hens started laying last week and the 3rd hasnt. I just can't figure out which one between the two is laying! (One I know is for sure) I was wondering if there are good things to look for to tell the difference? They are all aproximately 4 months old Here's the first one : Dixie Chick And number 2: Soar Thank you in advance!!
