Searma hens head all reddish purple

[rarebreedhen]

I've gone out to feed my hens to fine my serama rooster dead and serama hen very weak and has a reddish purple colour on her head. She is very weak. She's drinking but not eating. Any clues to what it is?

looks like cyanosis. any respiratory symptoms? illness?
what did the enviroment look like when you found the dead rooster? signs of trauma?

Perhaps heat stress?

Perhaps heat stress?

No, I live in Ireland and the heat is never a problem. I dont know what it could be, her vent is clear and I can't feel any obstruction. I doubt she'll make it.

Pictures?

 

[rarebreedhen]

This is her, she's still weak but has eaten a little.

what about toxicity? did they get into something?

Could they have been attacked by a predator? Did the dead rooster have any marks on his body? Is her eye swollen? The comb looks like it has been pecked or injured.

He was dead in the coop with the others. What's cyanosis? Can she be saved?

cyanosis is a dusky red, purple/blue color (cyan) that happens when blood is deoxygenated. conditions most likely to produce low O2 levels include respiratory infection, severe sepsis (wide spread infection), anemia (blood loss, iron deficience, protein malnutritionl) to name some.
the underlying cause needs to be discovered but you can start ruling some things out. I’m not an avian vet but in absence of clear signs of respiratoryinfection (nasal discharge, gasping, cough) or signs of anemia (blood loss, black sticky stools, abdominal bloating with loss of appetite for anything oral, infestation with parasites ) I can’t offer advice. I hope one of the experts here can better help. Keep her warm, offer fluids with electrolytes and isolate from flock in the meantime b
