I have a young buff sussex female, bought POL about a couple of months ago (along with a light sussex to keep a recently bereaved bluebelle company) for the past few days she has been making a funny noise like a sort of short alarm call/squawk and sometimes she shakes her head a little after it sometimes it's like she has sort of coughed and shouted at the same time? at first thought it was actually an alarm call but you can hear her in the coop at night when shutting up for the night it's intermittent but is becoming more frequent she looks ok and is eating, perhaps not as enthusiastically as her two chums tho any ideas??
