My hen, Penny has developed a hard, white, pea-sized cyst on her eyeball that isn't moveable and causes her pain when her eyelid is touched. It's developed over about 2-3 weeks. She has slowed down quite a bit lately, moving from #1 in pecking order to almost the bottom in a flock of 12. She's eating, drinking, and pooping just fine from what I can tell. Everyone in the flock appears to be very healthy after thorough inspection; no bugs, no worms, no cysts, and just finished up a molt. Penny however, can't seem to get through her molt. New feathers are growing, but are coming in very slowly. I live in a pretty mild climate on the west coast, but lately have been in a cold snap (some of you might laugh at the whopping 30s we've been dipping into). I've searched the Internet high and low, byc included and have found a whirlwind of answers. I'd like to start by saying that other than her molt and eye cyst, she appears physically healthy--no scabs on her comb or anywhere else, no critters, nada. She's still laying eggs about once per week or so, too. I fear she may have a cancerous tumor based on the behavioral change and lack of cyst movability. I should also mention that she's a little over 2 years old. Any ideas?
