I'm having the worst luck with my chickens. Earlier this summer lost all but one to an attack, took in a chicken from my mom and bought 3 pullets. The pullets had coccidiosis and I was able to take care of it as well as save the last of my original flock from the injuries she sustained from the attack. then found out the chicken i saved from my mom was aggressive and i found one of the pullets dead (this was after months of waiting until they were large enough to deal with her and they all seemed to get along. After getting rid of the mean hen another pullet hurt herself and nothing could be dome. I added 2 more pullets and things went great until today I found the last of the 3 pullets in the coop trying to lay an egg and bleeding from the vent. She hadn't started laying and hadn't acted strangely until today. She's been running around with the other chickens and eating. Today I watched her trying hard to lay an egg, puffed up and looking and sounding miserable. I put her in the tub and washed her back end and could see her vent is swollen and prolapsed. She's in a kennel drying and I'm not sure if i should put lubricant around it, try to push in the prolapse or what. Any help would be great.
