Ok so I bought a chick from a lady who says she only sales healthy birds, but my bird had blood in her stool the first day tried nursing her back to health eventually the lady swapped her out for another who had the same problems with in the first five min of her being home (blood in her stool), this morning it was even worse this was when I first got her home, same amount throughout the day. this was this morning. The lady says that it is something in her environment that is stressing out her digestive system. this is what I feed them and I guess the one having issues was on some other feed. Would changing up their feed do this ?
