I have a three month old Nigerian Dwarf doeling. She has been somewhat unsteady since birth, not keeping up with her sister at all. She is frail and thin, although has a good appetite. Her legs have always been suspect since birth, i.e., thin and weak. She is not even close to as nimble on her feet as she should be. She did have a BoSe injection at birth, and has had Selenium gel twice since then. This morning I noticed her back legs bowing out a bit, and her back right leg knee joint going out to the right when she steps on it. She is wormed regularly and just had fecals done by MidAmerica, she was my only goat completely negative. She has free access to alfalfa, minerals, kelp, baking soda and grain. She DOES NOT eat much grain. She still gets a full bottle of milk replacer once a day. She eats a lot of alfalfa. I researched a little online before coming here, and found that this could be a calcium/phosphorus ratio problem, i.e., not enough phosphorus. Does that sound logical? If not, what else could be the problem? If it is a phosphorus problem, how do I get it in her? Is there a phosphorus supplement of some kind I could add to her milk? I have a Caprine Supply Mineral that is 1:2 Calcium to Phosphorus which is available to her, but I'm not sure if she's taking that. Thanks for any help you can give.
