We fed our chickens a normal meal of lay crumbles at about 4:30pm local time (Los Lunas, NM, where the temp today reached about 90°F with mild/moderate humidity). They seemed agitated when we fed them, but we didn't notice anything very unusual. Around 8pm, we heard a kerfuffle out in the coop and went out to notice that all our birds were on top of their nesting boxes, food on the ground untouched. Haven't even touched the apple chunks or meal worms we'd given them as a treat today, which is very unusual for them. When I put the apples up top where they were standing on the boxes, they ate them like crazy.
Possibly related to this behavior, both of our roosters' combs are turning purple toward the backs of their heads.
Our buff rooster gets frostbite easily in the winter, but it's been getting down to a low of about 50°F at night and the barred rock rooster also has the purple comb tonight and never gets frostbite.
Any ideas? We presume stress, but didn't see any evidence of anything other than a few ants and a scurrying mouse... their water is clean, flowing easily from the poultry nipples, and freshly changed out yesterday.
