I processed a bird I simply couldn't deal with anymore yesterday and found something unusual: backstory: Black sex-link pullet hatched early May 2011 VERY flightly and neurotic Highly stressed at all times HUGE size, outgrew her mother and father Had not reached sexual maturity (possibly due to the high level of paranoia and stress? Which, by the way was the ultimate reason I couldn't tolerate her anymore..sick of the stress she was adding to my flock with her violent thrashing and squawking any time another chicken walked by or I showed my face outside...she did this in an attempt to "escape" even when nobody was interested in her and nobody had ever attacked or provoked her... she has been this neurotic since hatch but I finally had enough of her upsetting the flock dynamic) My findings upon processing: she was still at least a month from laying by what I could tell, all organs appeared fairly typical except an enlarged and almost golden colored liver? I offer scratch as a treat, and not too often. A 25 lb bag lasts my flock of 25 (+/-) birds at least a month.... She was young, I skinned her so no scalding.... ? What could cause this? She was otherwise a healthy big bird? Her mother is a barred rock and her father was a buff orpington.
