So I noticed the night before last night that one of my hens (8 months old) was acting sluggish and keeping to herself. I picked her up and immediately noticed her crop was pretty darned full and hard. I did a quick check-over looking for any bugs, but she didn't have any lice or mites. No stuck eggs either. I decided that perhaps she'd just eaten too much, and gave her the night to rest, hoping she'd get better. The next day (yesterday) she hadn't improved. I made sure she drank water, saw her do it a few times; I also made sure she didn't drink too much at once because I know that water in an impacted crop can cause sour crop. The blockage didn't go down, so I tried massaging her crop yesterday afternoon, attempting to mash up the blockage a bit. This morning she still hadn't improved. She hasn't eaten anything more, her crop is still the same size. When she walks, she's wobbly and stumbles often. I did some quick research and decided that I'd mix a little olive oil in some warm water, syringe some into her beak, and tip her upside down and massage her to make her upchuck the blockage out. So I got all set up, got out to the coop, and tipped her upside down - and noticed her vent looks TERRIBLE. It did NOT look like this the other day. I did some more research, but the only 2 things I could come up with by typing in "swollen vent" is prolapsed vent or vent gleet. Her vent isn't bald though, she still has all her feathers there and none are soggy, just crusted poo; and prolapsed vent looks more, well, SWOLLEN than what she has. Or at least I think so...but I've never seen prolapsed vent in person. I have a flock of 40 chickens, all get locked up at night and free range during the day. Everyone has 24/7 access to layer pellets, they get sprouted fodder in the mornings, and clean, fresh water twice a day (I'm a stickler about that). No other chickens are sick. This is how she rests. This is how I found her vent when I flipped her over. This is her vent after I cleaned it off a little bit. I checked again and she doesn't have any eggs stuck in her. This is the size of her crop, between my fingers. Size still hasn't changed and it's still quite hard. What do I do??? Am I able to treat her for impacted crop still and hope that fixes her? Could an impacted crop cause her vent problems? She's so young and I don't want to cull her if I can help her!!!
