Crossing our fingers, but I think we finally integrated our mixed age flock. Our 10 wk old Amerucana has been in the 4x8 coop for a few weeks. Our now 6wk Orpington & 7wk Barred Rock spent the afternoon in the coop & are now sleeping there too. (I've only peeked in the window with a flash light 3 times & maybe once more before bedtime
)
We introduced the littles 2 wks ago & it seemed like they were getting really picked on. We kept them in the U-haul brooder box one more week and tried again. The second time they got picked on, but not as much. They were not quite ready to be out full time, but were too stinky to be kept in the house any longer. Last week we kept them in their box, placed next to the coop so the bigger one would get used to their sounds. At night I placed the brooder box w/ heat lamp in the coop while the bigger one was in it's hen house. Lots of peeping at first while the littles got used to "camping" outdoors.
Flash forward to today.....there was some chasing & a few pecks. Mostly the littles tried to stay out of the older one's way. We made sure they were all eating & drinking and even added the brooder feeder to help facilitate that. I also cleaned out the coop, changing all the shavings to help keep the younger ones healthy since I didn't own them their 1st 4 weeks of life & not sure how strong their immune system is.
The 1st & 2nd time the littles were in the coop (and placed back in the brooder box), I noticed that their droppings were really "off" the next day. The chicks acted fine, but droppings were almost bloody looking. I worried about cocci and had meds on hand if things looked worse. I wasn't sure if it was all the grass they had access to in the coop or the stress or the grower mash we had out for the older chick. It lasted only 2-3 eliminations and was gone. I did give plain yogurt to see if it would help. Wonder if anyone else has seen this issue after real world exposure?
Best of luck everyone...I am going to peep in the window one last time...
