Two days ago I picked up free hens from a Kijiji ad ... nothing is free! Yesterday I isolated the hen that has a very red, swollen poopy bottom. Her vent is continually contracting and I thought that her abdomen was quite firm. The previous ower said that none of the hens were laying anymore (about 2 years old) but said they were in good health when I picked them up. My first guess was egg binding, so she was brought in last night, given a warm bath, dried and put in a nesting box (in the laundry room) with a heat lamp. In the morning she was eating and drinking well and poop looked normal for a chicken. (did not see any worms). I gave her an electrolye solution to drink and poured some over the layers pellets and also added some egg shell dust to the food. This afternoon I picked up some liquid calcium and also put it in her food ... but white liquid is still running from her bottom and her vent is still very red, sore and swollen and contracting. I did let her out for a while with the other hens, just to help her integrate into the flock and be able to strech and move. I am not sure what to do next?????
