This morning when we went out to tend the flock, I noticed that one of our 26 week old, P RIR hens, Sweetie, (she just started laying) has a very large lump right in front of her left eye, as big as her eye. There aren't any obvious cuts/ wounds or bruising, nor is it affecting her actual eye at this point. The lump seems firm, does not seem to be filled with pus- it is the same color red as her face, and does not noticeably seem warmer to the touch, or squishy. She was vaccinated for Cocci and Marek's as a chick, and otherwise is a healthy weight, eats and drinks well and otherwise seems healthy. She free ranges, has daily supplemental layer feed, oyster and grit, corn and sunflower seeds, plus scraps, treats and spring water. Sweetie is good natured, and her energy does not seem affected. Her comb and wattles are red, and her poops seem about normal. I've shown her in a variety of lighting so you can see the lump from different angles. Please ignore the mud on her face and beak as she was a busy girl this morning, lol. Thank you for any suggestions on what we can do to help her.
