Hey all, I've been in the backyard chicken game for 2 years. I have a good setup with a very large fenced in area of 40/20 feet. Coup is open for chickens to come and go. I've had some issues with foxes and belief I'm now fox proof. I recently had a hawk fly through the bird netting, they killed a bird but couldn't get out. I had to physically remove the hawk. I'm hoping that won't be duplicated. However my question is this is the first time I have introduced two new birds to the two existing mature hens. The new one is laying and the other one should be close. Sizes are similar. There was a little fighting initially with one of the new ones. Then they avoided each other the rest of the day. My real question now is the night. One new one (older of the two new ones and the one which was fighting a bit with the two existing hens) went into the coup and slept on top of the feeding tube but not into the upper compartment. The other one I had to put into the coup but he stayed on the ground level. I am assuming they will all eventually go into the main compartment with the nesting boxes when they can all tolerate each other and avoid physical combat. Thanks for the feedback!
