I recently purchased,what was supposed to be a pair of roller pigeons but really turned out to be two females. The real problem is that one of them seems to have gone weak in the legs. She was perfectly fine for the first few days. She walked around normally just like the other one but now she takes really short steps and uses her wings to balance herself. Then, when she gets where she is going, she just lays down. My dad and I both, have had lots of experience in various breeds of livestock but this is our first venture into the pigeon world. Our best guess is that she may be vitamin deficient since her legs are just weak but not broken. I would really appreciate some advice from someone who has had alot of experience with pigeons. Thanks in advance.
