What kind of hens do you have? I really don't know for sure what I have probably mutts according to the feed store clerk, they were "all brown egg layers" mixes of RIRs, Australorps, Amercuanas and Wyandottes. They were approx. 2-3 weeks old when we got them on May 11th. So I think that makes them about 13 weeks old now. I was told that they should start laying at about 5 months...I can't wait to find that first egg.
Congrats on breakfast!
