The egg on the right is from my 1 1/2 yr old barred rock. The egg on the left is from one of my chicks I bought back on April 26, 3 barred rocks and 3 buff orpingtons. I later found 2 more small eggs today. 3 out of 6 chicks are laying and I know it's definitely both breeds. So exciting. Does anyone have an idea how long it takes them to get regular size? They are guinea size right now.
