ours are a couple of weeks old,..I lose track, maybe 5 or 6 weeks. Anyhow Mom decided yesterday she has no use for them, she went back with the other chickens. So they spent the night in the brooder. Today my husband built a lower perch for them in with the hens and I went and checked on them a half an hour ago,..3 were on the lower perch hubby built , 1 was on the low hen jump up and one more a perch higher and the last was up there sitting with my crazy red hens. I will go out early in the morning the keep bored hens from messing with them, but I felt like if the mom left them best time to move them on from the brooder to the hen house was now. If all is well I will let you know,..but I am not too worried, my husband has really shown me how nuerotic I am, I worry about things that are a waste of time,..if things work great, if not go back a step. So tommorow we see if it works,..if not brooder back to the goat house.
