I wasn't sure where to post this mods so it may have to be moved. Two days ago one of my neighbors Barred Rocks SOMEHOW wandered down here and got mixed up in my flock while I had them out of the run in my yard(she honestly just appeared among my birds without my notice). The problem is, my neighbor's bird looks exactly like my favorite hen. I tried my best to decide which one was mine, but now I'm not sure. Last night, the bird in question was the last one in the coop and once she finally went in she roosted on the second rung from the top(this would be a first) also, my rooster has been "after" her constantly(which is also new). She seems very different personality wise as well. Could these behaviors be the result of her starting to lay on the day they got mixed up or do I have the wrong bird? I know this seems very trivial, but I was(and am) very attached to this hen-she is the reason I ordered more Barred Rocks. I am really upset about this. We banded our birds last night so this cannot happen again! Is there any way for me to tell for sure?
