One of our Silver Laced Wyandottes (about 20 weeks old) is hopping around on one leg. The other leg she holds up close to her body and the toes are slightly curled up. She gets around fine by hopping, but she also lays to rest a lot... everything else about her looks fine. She is eating and drinking fine, (store bought feed), and even scrounges like the rest of them for a treat! I have been giving her polyvisol, twice yesterday and once this morning... and wondering when I should expect improvement if that is the problem. How can I tell if the leg is broken? What else sould it be? side note- my husband found a shell-less egg near her yesterday, and thinks it was probably hers... that's a calcium deficiency right? and... her name is "cutie"
