I just picked up my two new chickens at the post office. They (McMurray Hatcheries)shipped them much nicer this time, in a box twice a big as last time (for 3 chickens last time) and this box had a divider between the birds. I got two pullets (hens 15-22 weeks old). A Barred Rock (black and white) and another Black Australorp.
I was warned by Linda not to put them with the full grown birds right away, but to use a dog crate at first. SO I am using one of Skippy's crates for them. I expect to keep them in there a few days, then put them in the coop with the big birds.
So far, they are getting along great. They are cooing to each other and the big birds are staying near the crated young hens. My big hens have been pretty skittish and stay in the woods under cover when they go out of their coop now. I am not letting them out as much as before as I'm skittish too.
