I have 7 chicks, all 18 weeks old at this point. I am leaving for vacation in one week, and will be gone for a week. I have my neighbor keeping an eye on my girls. I will be so bummed if my first egg comes while I'm gone!!! I have a SLW that seems to be ahead of the others as far as maturing. Her face/wattles/comb are really red, and her wattles are filling out. I am keeping my fingers crossed that she holds off a couple more weeks.
