I have four 22wk old hens and thirty 15wk old hens. My 22wk old hens have come to the conclusion that our butterfly bush in our garden is way better to roost in then their coop is.

At around 7:50 or earlier, eastern time, it ends up being pretty dark around that time we will find one or two sometimes even all four of the girls hanging in the butterfly bush. We usually leave them for about another hour to see if they will go back on their own. A few nights in a row now we have either had to carry one or two of the girls back into their coop!
Is there a reason why they would want to stay outside and not go back into their coop? I just got one egg today from the girls so they are obviously starting to lay now. Could that be effecting their usual pattern? Is it throwing them off a little bit? We don't mind carrying them to their coop because it gives us an excuse to hold them
but is there anything wrong with this behavior?
Could they grow out of it? We never had this problem with them before! They have always gone into their coop at night and this is just a recent occurence.
