males more susceptible than females?

[cecigl]

I have chickens kept at two separate locations and started getting sick - shaking head, bubbles in eyes and lethargic- treated with tylan 50 about a couple weeks ago and seem to be getting better but I'm not there everyday. here at home I have six-week old chicks and now they are getting sick- mucus from nostrils and in mouth, raspy breathing and shaking head. I don't know what it is but I did notice that from the first group ALL the roosters were sick and worse than the hens and here the sickest one I'm pretty sure is a cockerel. So wanted to ask if anyone has ever had experience like this, just seems odd that the males are worse off and maybe it's a tell tell of a certain disease or maybe males are just more prone to illness overall. Any info would be great. Thanks.

Too small of a sample size to suggest males are more susceptible to illness than females.

Sounds like poor biosecurity brought the illness from one flock to the other.
One should always practice biosecurity when moving between flocks. Change clothes, use a boot wash and wash hands at a minimum.

With the small percentage of things that can afflict chickens, able to be cured by antibiotics, I really wish people wouldn't randomly administer antibiotics without knowing what is wrong with their birds.
Not only does indiscriminate prophylactic use of antibiotics render them less effective in the animals being treated but that excessive use also creates resistant bacteria in humans.
Every year, 2 million people become ill and 20,000 die from bacteria that are resistant to multiple antibiotic families.

Never treat a sick bird without knowing the cause of their symptoms.
