My 1 year old game bird has had diarrhea for the last 3 weeks. She also has not been laying (thought she was broody for a bit) and she could be laying internally. She laid a shell-less egg about 3 weeks ago. She does not appear to have all of the same symptoms as my black sex-link who definitely became and died of internal laying. Her abdomen is not swollen, however she is low energy and standing around all puffed up and her tail is down, but some days she is better than others. I have been trying to feed her egg yolks, finely chopped roast beef, and anything that she will eat. She has a very low appetite, but she is the most skittish of all of my chickens and she is kind of freaked out when I have to catch her. I looked at the pictures of poop posted here: http://www.chat.allotment.org.uk/index.php?topic=17568.0 Her poop looks like the one that was labeled, "could be worms or internal laying" Will it hurt her if I deworm her with drop-on ivermectin? I understand that she may be laying internally and there is nothing that I can do to help her if she is, but it has been about 3 weeks since she laid. Wouldn't she be worse by now? She is better today then I've seen her in a couple of weeks. Wish I knew what was wrong so I could help her by de=worming, or prepare myself for her eventual internal laying demise. just for the record, my 5 hens have a large penned in area and free-range around my garden every day. They eat layer pellets and have oatmeal-yogurt for a treat in the mornings. I give them a cup of crushed oyster shell whenever I see they have finished the last cup, usually once a week or so. I also give them a handful of BOSS/corn/oats as treat twice a day. I give them avia- charge 2000 once a week and I put a dash of vinegar in their drinking water. Anyone have any thoughts?
