What type of flooring do you have it the brooder it's in? They do not do well on slippery surfaces like newspaper or cardboard.
It sounds like your Poult has whats known as Spraddle Leg. This can generally be remedied if caught early on. The legs must be secured
in their natural state for a few days to a week. For a Poult many times a band aid cut lengthwise will work. Bring the legs together until they
are at the edges of the padded part of the Band Aid. Wrap the sticky part around the legs and stick them together. This keeps the legs from spreading
apart as well as going too close together.
We use rubber shelf liner you can by cheap at "The Dollar Store"" for flooring for at least the first week. Smaller breeds we use it for 2 weeks.
They are easy to change and washable to reuse...
I hope that helps...
Good luck with her,
