I have had many many chickens over the years and have found on quite a few occasions that when moved to a new place it can take a while for them to go in on their own of a night. Normally after 2-4 days they get the hang of it.
However, nearly two weeks ago I moved my Orpingtons to a new house. Sods law this particular house/ run is a bugger to access for me. Its 4ft high, 4 ft wide and 10ft long, so crawling through on my hands and knees to put them away every night is getting tedious!
This has happened once before, years back, and it turned out there was red mite. the girls were obviously very reluctant to go into the house. This particular house is not only new but i creosoted the whole thing before they went in.
I have also tried putting a light in there as sometimes that helps them to go in.
Does anyone have any ideas??
