We bought 9 chicks about 3 weeks ago. The Welsummer, Ameraucanas, black sex link, and frizzle are thriving and doing great. 3 were silkies and the teenie one died suddenly a few days later. One is doing just fine, but the 3rd is really struggling. She is at least 3 weeks old and has barely changed size at all. A few wing feathers coming in but thats it. She was starting to get knocked over quite a bit by the faster growing chicks so I moved the smaller chicks to their own brooder. She sleeps a lot and isn't as active as the others. Then about 3 days ago I noticed her vent was poking out and looked a little infected. I've been putting a little antibiotic cream on with a cotton swab, but what else should I be doing? She is now crying/chirping most of the time and really struggling. She does eat quite a bit, but I only see her drink sometimes. She's pooping but it seems painful and often gets crusted on her vent. I'm really worried I'm going to loose her. Her swollen vent (its shiny due to the antibiotic cream) Size comparison to our other silkie She's trying really hard to live Thanks for your help!!
