Wondering if anyone has seen this in a comb before? This Leghorn hen is prob about 6 or 7 years old. I was considering making her into stew soon as her egg production is poor. I noticed her comb becoming swollen a couple weeks ago and then noticed this today. Not sure if the comb tore and it dried blood or if it's necrotic tissue. Not sure if I should just cull her and bury her or if it's ok to still stew. She has been showing no other signs of being sick.
