Hi! Thank you for asking. The last one to hatch with the naval protrusion is another Swedish Black. I apologize for not replying about that before now. That chick is doing OK so far. It doesn't like being alone but I worry about putting it in with the other Swedish Black and Isbar. The protrusion has hardened and dried to the point that it feels like a thick scab. It's had pasty butt once but I cleaned it quickly and it seems to be fine. I am keeping it's brooder as clean as possible and only using puppy pads with shelf Liner on top. I am hopeful that this will reduce the possibility of an infection.
The other chicks seem to be growing up and doing well. I was worried about the last CCL cockerel since it hatched and unfortunately I did lose him. He seemed to be doing better and better so I started thinking that I was overreacting, like I oftentimes do. One day he slowed down, a lot, even for him. I scoured the internet and finally decided that it was possibly from his naval (he always felt bulky right below his naval) and I found a mention regarding Tylan. I just so happened to have AmTyl on hand so I immediately started him on it, but I lost him that same day. I was holding and loving on him the evening before, so I worry that caused it, but I don't know. That has made me super worried about this Swedish Black chick. Everything I could find about mushy chick mentioned that it came from a dirty brooder or incubator. I cleaned the incubator with ammonia and then Bleach (not together) and I keep the brooder as clean as possible, in my opinion. Other than making a new brooder that has the chicks walking on wire, I don't know what else to do. These chickens are breaking my heart, but I wouldn't not have them. I figure that I just need to do the best that I possibly can for them and learn as much as possible about ways to be a better keeper to my chickens and ducks (and hopefully geese soon!)
