I've been searching everywhere for help with my flock. over all my flock production is down by 50% in the last month. lets put it this way i have 50 laying hens and now am only averaging 19 eggs a day. one hen i found with a blue comb and she is also leaving nearly glowing yellow diarhea (evidence on her vent feathers). She's lossing mass in the breast area too. Anyone had any experience with anything like this? I have contacted most of my egg eating customers and put them all on temperary hold for now until i know what's going on here and how i can control this. Most research i've come up with says treating with some type of antibiotics. Well, then the labels say not for laying birds. So far i haven't had any losses but would like to nip this before we do. Also, if it comes to having to give antibiotics, can we still incubate the eggs since we can't eat them?
