Sooooo, I bought 4 "laying hens" from a guy on Craigslist, who said the hens were all laying and were just over a year old. It's been 9 days since I brought them home, NOT 1 EGG!!! I contacted him a few days after I brought them home and he said to give them a few days to get settled. Is 9 days long enough to expect them to be settled? Is this normal?
