We have a 5 month old Red Sex-Link (1 of 3) - a few days ago we returned from our vacation to find our biggest girl sitting in her coop on her butt like a penguin. She had been sitting there for a while since her poop covered her bottom and her feathers in the area. Our next door neighbour had been taking care of our girls while we were away (topping up the food & water, cleaning the coop and collecting the eggs). He said a that the day after we left she had been sitting like this. She cannot seem to move her legs, she uses her wings to try and steady herself and keep herself upright. Since we got home we moved her into a box in the basement with food and water at head level so she can reach it better. Two days ago while she was in the house I had to force feed her and dip her beak in the water to get her to drink. She then seemed to get a little stronger and was feeding on her own. The next day I she was the same, I put her outside to get some fresh air (and to air out the house) but she didn't get any better and didn't move at all. Last night my husband brought her into the back porch for the night in the box. Today her breathing seems laboured and she constantly either falls asleep or passes out after she drinks just a little, I've had to go back to force feeding her. The poor thing stinks so bad so my husband and I took her to the laundry tub to rinse the poo off her feathers. Her stomach seems very distended (sp?) but we don't know if that was normal or not. I don't know the terminology, but the part that the egg comes out of is a bit red and seems bloated as well. While we were rinsing her butt with the warm water something yellow, runny and very smelly was squirting out of her. Her poo had looked normal up until this last incident. We have the 3 birds, they have an A-frame coop that they live in during the night and in the morning we let them free range in our yard. We live in southwestern Ontario, Canada. We are also having a problem with rats who have moved in under the coop. Could the rats have bitten the chicken and made her sick? Should we be worried about eating eggs from the other chickens? The other 2 chickens haven't laid an egg for us since we've been home (our neighbour said he got 7 eggs while we were away). Can anyone help us? We don't want to euthanize her if we don't have to, but we also do not want her to suffer. I can send photos of her if needed.
