Is it too late for a 5 week old splayed leg, if that's the problem??

[Paula 53]

The older one is now walking around pretty good and getting better every day. I am still considering the possibility of slipped tendon but with my rubber band set up on her legs I see her foot almost pointing straight forward and sating underneath her. It appears to be correcting the problem so I'll keep it on for a couple more days. Improvement is amazing.

The little one is a little better and showing slight signs of possibly recovering. We are alternating vitamins and antibiotics. It has not walked for about 10 days and was on its side for most of those. I was going to cull her last night but decided to give her a little more time. I'm trusting my instincts and can tell there is good life still in the little bugger. We may just get her back on her feet again.

Antibiotic is oxytetracycline
Cocci treatment was Corid

From what I understand Cocci would have killed her long ago and probably was not the sickness. Also no bloody poops.
Mareks could be it but should Marek's of killed them. I mean the little may not make it but the bigger one appears to be making a full recovery.

Anyway, thats where we are at.
