What is Mareks? Ya it doesent seem like its splayed to me. The toes do seem more curled then they were before. But everything looked normal before..and it was walking perfectly till like 3 days ago so I dont know what the deal is. I didnt know they made shoes to straighten their toes? Is the chick too young for them? How fast does action need to be taken to correct it? Will it still survive, it would just be crippled?
I just did a quick google search for mareks and it looks like in most pics the chickens legs are splayed in every direction and it mentions paralized legs and wings. This chick still keeps its legs under him, and it can still pull its legs and wings back if I move them so it can still feel everything. It still can walk to, it just walks funny.
Marek's is a gradually paralyzing disease of which there is no vaccine or cure for it. I'm not a vet so can't advise further except some chicks are prone to it and others are hardy and immune but carry it for the rest of their life. And if it's Marek's you'd have to quarantine although all fowl are probably exposed if that's what it happens to be.
All bad news aside and if it's not Marek's, the chick needs shoes - you have to make them and tape them with soft tape to the toes. There are videos on youtube and I'm sure some pics on BYC threads but just don't know exactly where that show how to make the little cardboard shoes. You can't just "buy" them although I bet a lot of BYCers would purchase them if they were commercially manufactured. The thing is that there are so many different sizes of toes so owners just make custom shoes themselves. One owner actually cut out toes on the cardboard and taped each chick toe on each cardboard toe. Do asap before the bones grow permanently crooked.
