Just joined BYC. We had one hen and one rooster, but today they flew out of the run area with a 4 foot fence. Just got them today they were about 10 months old. They were black silver tips. Do you think they will be back or should I just get some more? I will be installing a fence top on my run and coop areas to prevent this again. Any suggestions and advise would be greatly appreciated. I am new to the chicken raising thing. So I need some help please. Have a good evening.
