At this point I would like to thank all of you for the strong assistance. It reaffirmed me very much.
I have a few points to explain,
1- This problem occurs for me now for the third time. So three different generations of the same parents in different time phases and with different holding conditions.
2- I use the desert sand not to heat but only as a ground cover to make it easier to clean the chicks.
3- This disease has occurred before the use of sand. Very wise guesses what the sand can do, but not in this particular case.
4- The first sick generation of about 40 chicks I tried to treat with Salmonella therapy. I used ciprofolxacin and then florfenicol, with no real success.
5- The second sick generation of about 27 chicks I have tried to treat with coccidia therapy. I used amprolium and then artemisia, even without relevant breakthrough.
6- In this last generation of about 37 chicks I have used mixed antibiotics such as ampicillin and ciprofloxacin in the water and curcumin and cinnamon in the feed. With very little success, the death rate has fallen slightly, but the chicks remained weak and very warm needy. They do not gain weight.
7- I have a heat lamp, but I can not use it continuously, because the electricity there "Gaza, southern Israel" goes on and off in 8 hours cycle, and so i have to use a Battarie that does not live long. Actually in our weather, healthy chicks are doing well without heat lamp, since we often have temperatures between 80 and 88 ° F.
8- In between I managed from the same conditions to raise chicks, which grew very healthy. The trick was to raise each 10 chicks separately in a carton. After 3 to 4 weeks healthy together and ill together.
Hints,
- Older chicks do not get sick, also when the chicks are a little older, they will not be infected.
- Younger chicks, once sick, never really heal and always remain weak and emaciated.
- Yes, I used a starter Matmor Feed.
By the way, I thank the Akrnaf for his helpfulness. The unreachable neighbor in the same country. I guess I will never be able to see him. It separates us borders and much more. What a crazy world. We are very close but very far. I was hoping to be able to hug him and everyone in my arms, except that these are only dreams of a child. A lot has happened. The question is if man can walk over his wounds, the answer has a bitter taste.
I wish you the best Akrnaf, you probably can not do anything for what determines our world.
Sorry that I have deviated something from the topic. Would be good if we stick with it.
