Chicken staying in a neighbours coop!

Morning all,

I have had 2 chickens for the past 3 1/2 years and they both get along fine together.  They have 4 friends from a neighbouring farm and they will come and find one another when they are let out of their respective coops each morning.  They also get along fine with their 'friends'.  They have acres of field to explore with constant access to food and water at all times.  Suddenly, over the past few days 1 of my chickens has taken to sleeping in my neighbours coop.  My coop is the same style as theirs, it is clean, free from draughts, has a supply of food and water etc etc.

The first time I was aware of this is when she didn't come home one evening.  I had a good look round for her but when she couldn't be found, I put it down to a fox getting her.
They day after she appeared with her friends and carried on as though nothing had happened. I phoned my neighbour who confirmed they had 1 more in the coop the previous evening. I asked that when they closed their coop that evening , could they oust mine (hoping that she would find her way back).

On the 2nd evening I left my closing up until a bit later in the evening and still there was only 1 chicken.  It was late, so I didn't phone my neighbour.

Last night (3rd evening) still 1 chicken in the coop.  It was late again, but I did phone my neighbour who agreed to oust my chicken.  She called across the field that separates us that my chook was on her way back............15 mins later she still hadn't arrived. I phoned the neighbour again, who looked out of her back window to find my chook sitting on top of her coop.  I went to fetch her and physically carried her back to my coop.

I realise this is quite a long post, but has anyone any idea how to teach my chicken that her home is in my coop and not the neighbours?  Would keeping her in the coop for a couple of days work?

I look forward to your suggestions.......thanks 

Yes, that would seen like a good plan - I'll get the run set up and see how it goes over the weekend - thanks!

Hi,
I have had the same problem with my leghorn who loves to sleep at my neighbours with their white leghorns.  My neighbour says that it is because she likes to be with similar hens, but to me it is very irritating as she will eat at mine and lay at the neighbours! The only solution I have found is to (Ground her) keep her in my run with my other three for a fortnight as if she was a new hen and then let them free range.  I also have left it later before locking the girls all up and some reason, she now comes back.  Good luck and let me know how you get on! 

Glad you have had a good result.   

Glad it has worked
