I have a nursery pen,( with hen and two chicks), which is a subdivided section of the big run. There are 18 laying hens in the big one. I have been trying to figure out when and how to integrate them,(What me worry? lol) When I went out a few minutes ago to let the big girls out to free range I noticed that one of the babies was on the wrong side of the fence. IN WITH THE HENS!!!! ALONE!!!! WITHOUT MAMA!!!! Nobody had harmed it at all. The only way to get the baby back in with mama was to open the hatch between the pens. I can't for the life of me figure out where the chick got through or under. But now I know that the chicks are okay with rest of the crew I guess they can start living together. It will be interesting to see if mama takes the chicks to the coop or stays in the nursery with them. Or takes them out free ranging!!!! AAAARRRGH! Now I'm worried again. I may have to spend some time out there lurking in the area, spying on them.
