We have three hens, with one from our original flock, and three that we purchased as companions for her so she would not be lonely. Our original flock was raised by us, and very friendly. After three animal attacks, only one bird was left from that flock, and she acted differently as a result--we think. She used to be more friendly and would come and hang out with us, happily pecking away. The other three birds were raised by someone else. One seemed friendlier than the others, and would come up to you. Now, progressively over the last several months, they are less responsive. In the past, we would call them, and they would fly to us. Now, they ignore us, and keep doing their own thing, with indifference. No real response from them. One bird was always suspicious and we didn't expect much from her. She acts like someone is going to attack her any minute. She turned broody, and is even more hostile now. But the others, I don't know what to think. They act like they care only for their own company, and not ours anymore. We give them treats occasionally, but it does not seem to matter.
