we bought 6 pure bred hens last weekend age 7 weeks,i was told to get them used to their home and where they are to sleep for about a week before we let them free range but they wont go in to the darkened section of the hen house when its dark they want to stay in the run cuddled up in a corner and so far each night we have had to pick them up and put them in physically,can someone tell us what we are doing wrong and how to fix this problem.
