My black cochin bantam hen has just started laying. She is 20 weeks old, and we also have a pair of 20 week old buff cochin bantams.(not yet laying). The eggs are so small, will they get any bigger?? I did not really want bantams when we picked these chicks out at TSC, but they were in a mismarked bin. Now, of course, we are in love with these little cuties. They are such loves!! Also, how good of layers are they?
