Hey everyone, So today I noticed that Owen, my six year old, has a pretty bloody spot on his tail. It seems like it's not coming from the train feathers, but the actual tail feathers underneath the train... I'm not sure though, there was a big splotch of blood and I couldn't tell exactly where it was coming from. He seems to be acting the same, but it just really caught me off guard. He's had to stay inside with the kids for the past week or so, I only let them out when it's relatively warm, which it hasn't been in a few weeks, so I've let them out when I can. Did he catch it on something and just pull out or break a feather? Is this something I should be concerned about? Thanks!
