I currently have 4 Large Fowl hens (2 black sex link, 1 Buff Orp & 1 Barred Rock) & 1 Bantam Game Fowl Mix (bottom of the pecking order of current flock) all currently 9 months old, I acquired 3 more "Americana" feed store chicks the beginning of September to replace a large percentage of my original "pullets" turning out to be cockerels which aren't allowed in my area. Coop: 8 x 8 inside & Run: 8 x 11. I have had the new pullets in a wire dog kennel inside the main coop for a week. Yesterday I tried some "together" time late morning. The larger hens seemed ok for the first 30 minutes or so and just ignored them, the Bantam who is quite a bit smaller than the 3 new pullets was relentlessly chasing and pecking at them while they hid in a corner. At this point the larger hens started chasing them. Since they didn't seem to be drawing any blood or being too aggressive I left to go fix lunch and let them establish a pecking order. I came back out to find the three 12 weekers huddled in a corner of the run. It is pretty cold here the past week, highs averaging 20 degrees. I did a few things outside while watching them, and finally went and put them back in the cage inside the coop after 30 minutes so they didn't freeze & they could eat and drink more. Later in the afternoon before sunset all the older girls were starting to settle down and get their spot on the perch, I let the 3 littles back out they ate & drank from the big girl food and water (I put the Game Hen into the cage for an attitude adjustment so they could do this in peace) I let them be until it was fairly dark and checked on them again. They were sleeping on the ground so I put them up on the perch with the older girls. This morning I went out & same thing they were huddled into a corner of the run. I took out a large cardboard box and fashioned a smaller opening for the little ones to run into to hide. I went home for lunch and it seems like that's where they have been for most, if not all, of the day. since it is closer to 45 degrees today I let them be in their box for now.... Is there anything else I should be doing to help them along? Do I ride it out for a few days if they seem uninjured? the high tomorrow is 20 again. They don't seem interested to try and fly away from the others or even to roost. I can hang additional water & feeders outside for now, but if it starts to snow soon I don't want them in a box outside... needing some advice!
