I have 9 hens (I think) they are 11 weeks old. A friend called me last night that she had 3 hens that needed a good home, they are any where from 1-2 years old. All my chicks are free range. When I put them in the outside coop yesterday, one of them flew right over the six foot fence. The other 2 went into coop and slept, this morning they all went out and now the other 2 are missing. I saw one in the woods, but could not get her. I have left the door open so they can come back in..........or do you think the 3 of them are lost for good.HELP
