Hi , I have a pair of mute swans that are 4 years old. They are getting ready to nest for the second time ,& they seem to be doing great. My concern is the female has a large lump on the bottom of her foot. It doesn't seem to bother her , but it bothers me. I don't know if I should catch her, & take a look at it? Also in the summer she gets grass stuck under her tounge. I take it out a couple of times a year. Do I need to do that or will she be fine if I let it go. ? I love your sight , & have learned alot about my swans. Thankyou Tom
