I got a baby silkie chick from my neighbor who hatched the for me in his Sportsman. One had one Spraddle leg. I did nothing because nothing i ever did before worked. I did have a lot of babies and kept them in a small area so they were close togethe for about 5 days. He totally recovered the leg on his own. This was first for me. I picked up some more of chicks hatched two days ago and put them in the same situation. Yesterday a blue had both legs going out and a buff had one. Tonite they are both getting around well and I see them really trying to keep their legs up under them and doing a good job at it. From the looks of it they will recover too. Glad I didn't cull this morning as I had planned.
