Yay!!! Congrats!! Its so exciting when they start hatching!! Can't wait to see baby pictures!!There are babies!!! I must have miscounted what day I was on because I wasn't expecting them until tomorrow. I guess I shouldn't have been so worried about the air cells, they seem to be pipping and zipping just fine. There are at least 7 out and I think a few more were zipping. The one thing about the hatching boxes I don't like is it is very hard to see inside because I made the boxes using plastic canvas. I will take the chicks out tomorrow morning and post some pics.
