My five month old copper marans rooster has a large lump on the back left side above the hip. I don't think it affects his walking and it didn't bother him when I checked it. Any idea what it might be??? On the bright side, his girls, two ameraucana/marans crosses laid their first eggs at just under 5 months 
I was very surprised, and they have been laying like troopers ever since.
