Hi, Kinda new to all this! I've got four laying sex link hens. All have been pretty healthy. Had one get her eye pecked by the dominent hen so treated in isolation, she got healthy and happy, and back to the normal! Yeah! The dominent hen which we call Dom has become very larthegic, distant from the flock, greenish yellowish, runny diarehha. I have had her isolated to watch her and see what and if she is drinking and eating. The first day she drank like there was no tommorow. Now (into the third day of isolation) she is drinking very little if at all. She has access to layer crumble. Nibbled a bit the first day. Now won't touch it. She is still eating mealworm treats, cause that's their favorite treats. I don't want her to become totally deprived of nutrition. I tried to give her plain yougart, scrambled egg with olive oil, buttermilk, bulttermilk and cornbread, she won't touch it. She is not really showing any symptoms other than she's not laying, very larthagic, the diarehha, fluffed feathers, and loss of appetite. Last day before isolation saw her trying to lay an egg, with no sucess. Her breathing seems normal, crop seems normal, no foul breath. (No pun intended) Crop and wattles normal no paleness. No signs of parasites. Legs and feet look healthy. No feather loss. Checked her vent seems normal. With the diarehha her bottom got a bit nasty so took her and cleaned her up. Sure that didn't make any feel anything but violated. I made sure she was dry before putting her back in the isolation pin. I have newspapers down and change quit frequently, a low perch (which she isn't using much) and a box with D.E. and pine shavings for warmth and comfort. Tempertures and climates are warm and dry, as she is inside. Oustide it's been cold and raining with humidity. I put vinagar in their water. They do free-range daily normally. I noticed last night that 2 other hens have yucky bottoms too and egg production has dropped to 1 egg per day. I was getting 3 per day. Otherwise seem to be normal. I dismissed this to all the crazy weather we have in KY. One day it will be 60 degrees and then 23 degrees the next. It messes me up. I can't imagine what it actually does to nature. I have tried to look into this but everything is so contradicting and I don't want to be treating her for the wrong thing and make things worse. Any help would be appreciated.
