I had three B.O hens and lost two to a dog attack a couple of weeks ago. They were about seven months old and one had been laying for about a month. So I went and bought some older hens (suppose to be this years birds?) in order to try to regain something for the year. So I now have a few that are suppose to be laying but I'm only getting like one from them. I know which one is laying so I guess I am trying to figure out if I should worry or I just bid my time because of the season. Thanks.
