Hi I was wondering when they hatched was the nest box slippery when babies are born they need sure footing under them or the legs grow out instead of under if THER a week or two get a small piece of sponge Put two 'X marks with a knife and place THER feet into the x' s you cut make sure the x's are an inch between the two x's and say a prayer see if that leg is back under the squab if it dosent work after a week to ten days then you have no other choice but to dispatch it rather than let it suffer always make sure they have some thing from keeping them from spreading there legs grass inserts for the bowls and hay or anything too keep there foot under them good luck i hope it works for your squabs .. we
