March 16th my chickens will be 16 weeks old and when I went to clean the coop, they had made a mess! They’ve never rooted around in the coop in their shavings and today they had the pine shavings in areas I had a ledge to keep shavings out of. I think they might of do that last night, because I noticed they went in the coop earlier than normal. Question, are they looking for a place to nest? I have their nest boxes blocked off until this weekend, is when I planned on unblocking them. At 16 weeks, to start laying, just seems young! They’re still eating chick feed, their feed will also be switched this weekend.
