I guess to rule out all areas that could be the problem. And maybe to find out a common thing that you all may be using that could be cuasing it, I think it would be good that you all post:
PIctures of the boxes your chicks were shipped in. It would also be good if someone could post pictures of the shipping boxes they got from a different hatchery. Since people seem to keep blaming weather on these problems, I think it would be good to compare the different boxes to hopfuly either do away with the shipping, and bad weather or to maybe figure out why other hatcheries arent having this problem while MM is.
List what type of brooder you are using. Where the chicks are being kept (in your house/garage/barn/coop)
What are you feeding them?
Did they get vaccinated?
what source of heat are you using (light)?
Are you putting anything in their water?
how many did you start out with and how much space did they have?
What are you using for bedding, (wood chips, paper)
I have a hard time with believing that these chicks were sick because of negligence on the buyers part. Chicks have been shipped in the time of year for a long time, and obviously there hasnt been this many problems before or they wouldnt still be offering to ship them this time of year. And I dont know about some of you but if I order chicks, which can add up to a huge chunk of a pay check, I would be doing everything I can to make sure that they live.
I also have a hard time believing that it is normal to have more than two or three chicks die in a order. Yes these are chickens, and we do know that there are losses in the husbandery of poultry. BUt you should NEVER think its normal when you loose that many chicks.
I do believe that there is something serious going on with chicks from this hatchery. I dont think it is anything like Avian flu, but either something to do with inbreeding,poor conditions of incubators and hatchery its self, or diseases. I dont think that MM would take the heat wilingly for the problem, and will or may already be doing what they can to cover or hide what may be causing this, in the invent of Dept. of agriculture coming and inspecting. I feel that everyone who has these chicks to take a lot of pictures and post them on here that way there is a paper trail. If everyone who has been dealing with this would come on here and post pictures, vidoes, and everything done on your part to rasie healthy chicks, would be a lot better than trying to go head to head with them your self. thet can easily ignore, and side step people individually, but if you all went together then you stand a better chance of getting everything fixed. The vidoe part would be good if someone can do that because it leaves a record that actually shows the chicks symtoms, pictures are worth a thousand words. I am going to keep a close on on this site, as this is a huge problem that is also very scary.
