Sometimes my chickens make me scratch my head??

I have 4 chickens that well, dont follow the flock. They also dont seem to be the brightest of birds, but to each their own I suppose!!

I took these pics the other night, they are pretty dark, well cause it was pouring rain, and it was about 11:00 at night!

Three birds roosting on top of the coop!! Did i mention it was pouring rain out??

All the other birds, were snuggled up in the coop where they belong! But these four refuse to go in at night. Maybe they needed a bath??:D

Hmm, perhaps they heard about those Scottish chickens who recently made a bid for freedom, and thought they would try a little adventure of their own? Then, of course, Richard told the story about the Californian chickens living out near him ... That's it - blame Richard! :D

thats very strange. sometimes our chickens don't like going to bed so i have to catch them :rolleyes:
maybe they get pecked by the others if they try and go inside? if it continues, as a drastic measure, try and construct another little coop for them and see whether they will sleep in that one?
