My mixed flock of 12 are 9 weeks old. Eleven of them roost very close together on about 2/3 of the length of the roost. The roost is a 2x4 with the 4 side up. The other (Cuckoo Maran) sleeps under them on the poop board which is about 9 inches below the roost. Is this part of the pecking order thing or do you suppose she just prefers the wider surface under the others?
