Infectious Bronchitis repricussions?

[bhawk-23]

I never confirmed the sneezing and congestion was IB but I did treat the whole flock with tylosin. All but one hen has stopped sneezing for awhile now. The one sneezing hen is just on occasion. They are all eating well, poo looks normal, laying well and overall a healthy flock.

My concern is that I am seeing some shell abnormalities on occasion. A slightly odd shaped egg, rough and thinnish shell, but lately I am seeing more calcium deposits. The egg whites are normal.

They eat layer crumbles with free access to calcium.

If this does seem like the aftermath of IB, do I need to worry about anything else?

If not, should I be looking to their diet? They have been eating more layer crumbles since being in their run. Avian influenza is near so not as much free ranging as they are use to.

My concern is for a friend who will be coming to check on my flock twice daily for 9 days. She will be handling my roo each time. She has a flock of her own.

Thank you!

Are you sure it's IB? Tylosin will not treat IB since it is a virus. Mycoplasma Gallisepticum (MG) can be treated with Tylosin with good results.
Wrinkled eggs and watery whites are typical for IB infection and it quickly spreads through a flock.
It's also possible that birds can have 2 respiratory diseases going on at the same time.

I highly recommend that you practice strict biosecurity with your flock. Respiratory diseases can be easily spread to a "clean" flock via clothing, shoes, person, tires etc...

Thank you, I'll read the link you gave.

I'm not sure if it was an infection or environmental. It started when the weather turned cold and I had made some changes to their environment. I chose to treat because a couple sounded congested and I was worried.

If a calcium issue is not direct effect from IB, and she is only sneezing at night maybe it's time I remove the plastic from the run to see if that helps.

It might be due to an environmental issue, such as; ammonia fumes from soiled bedding, improper ventilation, inhalation of feed dust, dust from dust bathing, mold spores inside the coop, pesticide use, pollen. All these can be corrected or eliminated.
It would be a good idea to remove the plastic from the run and observe all your birds for a few days including the one that's sneezing.
