Hi New to this but everyone seems very helpful so here goes! We've got some chooks that just won't roost! (32- 34 weeks old) We've checked their roosts are wide enough and they are 2 at different heights but they just won't go in their shed much at all. The have a large enclosure for nights but are out during the day when they lay in the garden (fine except when we might be away for overnight and then they don't lay in the boxes, just on the ground!!). Anyway, they just stay huddled on a large paver at the door of the pen and 'roost' there! Even when it poured for days and nights recently they just stayed and got wet! Should we be concerned for them or are they probably fine and I don't need to worry!?? Also, we bought 2 new chooks yesterday and when we got home we discovered 1 is missing a lot of feathers. She seems to peck at herself a lot. She's quite small (supposed to be 18 weeks, but the other one is much bigger!) We had a look at her this morning and she's got mites so is that why she has been pecking herself?
