I noticed after my chickens laid their first egg last week that whenever I check on my chickens, they run to me (they have always done that) and will kneel down and flap their wings back. the runt started it first and few days later all five of my chickens started doing it. they don't exhibit this behavior every time i come check on them, but if pick one up, she'll kneel down flap her wings back. all five do the same thing if i pick them up.
