Sounds like it could be an upper respiratory illness. There's also a possibility these chickens are suffering from heat sickness.

Your hen likely has more than one issue. And, yes, it could be Marek's in spite of the vaccination. It only prevent tumors, not the inflammation of the sciatic nerve that can cause paralysis. If this chicken also dies, have her body tested so you will know. Managing a Marek's flock, you need to...
Calcium supplements, whether citrate or carbonate forms, are concentrated, unlike oyster shell and egg shells. Hens are reacting to individual cravings for calcium and they consume the oyster shell or egg shells and quit when they feel satisfied. They can't do that when we stuff a supplement...
I think you and I have both covered all the bases we can think of. One other thing that affects shell quality is molt. It may seem that it's early yet for chickens to begin molting, but the days are growing shorter and it's triggered two of my hens so far to molt.
I think holding the line and...
You don't mention where you live. If, for example, you live in Panama or Brazil, it would be hot for much of the year. Heat stress can cause these shell issues. Other forms of stress can also. If you live on a busy street or have a noxious dog barking next door, this can affect egg quality.
I'm...
No, ovulating twice in a 25 hour cycle is not normal nor healthy. Let me clarify the length of time I usually give one hen the calcium citrate supplement. It's normally for a few days to two weeks max. My hen Ethel was heading for an egg binding crisis. That's why I kept pumping the calcium into...
Give the chicks a little extra sugar in their water for a quick glucose boost.
What is your water source? Sometimes when you get sick baby chicks, it can be from untreated well water or from ground water contaminated by fracking in the area. I suggest switching to bottled water for the next...
It could be coccidiosis. Do you have Corid on hand? If so start them on it.
You really have not provided any information other than your chicks are sick, so this isn't a diagnosis. The incubation period for coccidiosis is around seven days, so if the chicks have been with the broody for seven...
Don't get hung up on measurements. Just pour dry feed into a five gallon bucket and cover it with warm water. Add a splash of ACV to start it off. This initial ferment takes about 36 to 48 hours. Then you feed one cup per chicken per day. Some chickens eat more, some less. It's not high math...
Two things come to my mind that can cause this type of lameness. One is a riboflavin deficiency and the other is lymphoid leucosis, a virus similar to Marek's. The first can be treated with vitamin B complex for about six weeks. The other has no treatment and will kill the chicken.
Another rare...
Since ear bud covers are rounded and made out of an inert substance, it should pass through the duck safely without any action on your part. However, if you're uneasy just letting nature take its course, the best thing to lubricate the digestive tract is raw egg white. Just give it to the duck...
The only way to get a postmortem would be to send a dead chicken to a state lab for a necropsy. We can only take wild guesses.
Were these two hens that died spontaneously commercial breeds? Sex links are bred for prolific egg laying. They spend two years shooting out tons of eggs, and then...
