I had hen die about 3 weeks ago who seemed healthy, she was fine that morning and the afternoon was dead. I checked her out and her crop seemed full so I thought maybe she ate something and got impacted. Tonight another dead hen who was fine acting this morning. Also no one has laid eggs in 2 weeks or so at all. I thought maybe the heat but my nephews are laying and others I know of are still laying. No egg shells laying around like the chickens are eating them and I have 2 separate pens, one that has silkies that I'm not getting eggs from either. Any Ideas?? I don't want to loose any more. I wormed with Pyrantel about a month ago a pea size drop per bird, should I try another kind?
I've been throwing them veggies from my garden, could it be that?
A few weeks ago, I had a similar sudden, unexpected death. Second or third, in a month. Someone here suggested calling the Oklahoma Dept. Of Agriculture. After the second, I did (this must be done, right after finding the dead bird, bag it, and put it on ice, or in an available freezer) this, and they sent a fellow out, in a couple of hours. This was the Thursday of July 4 weekend, so, it took a bit of time, to get the necropsy report back. Here is a copy of what I got back from them:
We do not have final results on your case. However, the preliminary results received late Friday, indicate Mycoplasma. They are still running more tests, so there may be more information to follow.
If you are still having birds die and the problem seems to be getting worse, you can begin treating them now for Mycoplasma, and then when we receive final results, we can determine if there are any other problems, and whether there may be any other antibiotics suggested to be better.
One effective antibiotic, that is found at most local feed stores, is Tylan50. It states on the label, it’s an injectable antibiotic. The easiest way to administer this is to put the antibiotic in the water. You will want to put just enough water in with the antibiotic that you know they have gotten the dose. Then once all the water is gone, replenish with fresh water as needed. Recommended dosage is 1-3 CC per 10 LBS of birds. If you are currently not having lots of other birds die, then the lower dosage would be fine. However, if you are still seeing a high death rate, then you would want to hit them with the highest dosage possible and for a minimum of 10-14 days. After 14 days of treatment, if you see some birds improve, but it seems to be reoccurring, or not improving, you may want to consider getting rid of those birds in order to protect the remaining flock. Some birds may be considered chronic, and just not able to recover.
I had one duckling die, after this, but there was strong indication of heat, being that cause, and that happened late on a Friday, where the state could not come out, in time to do a proper necropsy. Otherwise, the single treatment of the Tylan 50, seemed to do the job, quite well. I'm not saying that this was the issue with your birds, but, you could call the state AG department, and try to get some help. I found them to be very helpful.
