OC Chick
I'm so sorry you're having to go through this. I just found this thread yesterday and read through it all. You are an amazingly caring and attentive chicky-mama! I loved your last video showing the aracauna come inside looking for treats!
I lost a few young hens last spring and never knew what it was. The last one was my silkie who exhibited the leg paralysis, so now I'm thinking this may be what was going on. After reading this thread, I'm going to be much more vigilant about keeping chicks away from the older flock for a couple months.. I'm thinking I must have put them in the same proximity too early. The adults are all fine.
Anyway, I came across this information this morning and want to share it with you and all others reading here for future reference:
