Hi, looking for some advice on one of my 3-year-old Leghorn girls. She's off lay and her comb and wattle have receded noticeably and are paler than usual. Other than that, she seems healthy - crop normal, feet normal, droppings normal, eating well and still bossing the others about (she's flock leader). She's not about to go into moult as she moulted about 5 months ago. The rest of the flock are fine - not a lot of eggs but they're quite elderly so don't expect loads (my two leghorns are the youngest). Any idea what could be causing these symptoms?
