ok....get ready then....here are a couple shots of my girls...give you an idea... ( the 1st pic, the BR girl in the back, has not started yet, notice her comb to the other 2)
by your pics, I would say you have a week to wait...?
My girls are 18 weeks old today. I have heard of people having eggs as early as 16 weeks. Some of my other girls have a ways to go yet. I'll post pics later today.
My RIR started laying at 20 weeks and 1 day. My production red didn't lay until nearly 23 weeks. First egg on Friday and none since then. I really thought the production red would be more of an egg laying machine. Turns out the RIR is my most reliable layer giving me an egg a day!
