Hi everyone, a couple of my chickens have, today, started crouching. My polish frizzle for example (who I am unsure of sex, but I think a hen) when I walk up to her to stroke or pick up, she crouches down and sometimes spreads her wings out (almost like she's sticking her elbows out?) none of my chickens lay yet due to age and/or sex. Can anyone shed any light on what might be going on?
