This is not meant to dirty anyone's name or to be taken as slander. This is information pertinent to TSC customers and they have the right to know what they are buying before they leave the store. If you do not know what MG or Mycoplasma Gallisepticum is, try googling "MG in Poultry" to start. It will bring up numerous good, informational articles. This is a run down of what I discovered today. You are free to double check my information if you feel the need, but I promise this is truth (for what that's worth from a stranger). The two Tractor Supplys closest to my town in my area have ordered from TownLine Poultry Farm in Zeeland, MI this year. THESE CHICKS ARE OUT OF MG POSITIVE BREEDING STOCK. I only know this because when I went to the TSC after classes today, I saw that they had started chick days and immediately ran back there to hopefully get some. Well, having learned my lesson ( i lost a whole flock to the disease), and noticing their waterers all looked as if they had antibiotics in them (color was off), I questioned where they came from and why the water wasn't clear. An employee informed me that they had started them on tetracylcine. I asked what was wrong with them, and he said nothing that he knew of. That just doesn't stack up. You don't give medicine to healthy animals. So i asked for the hatchery's number and spoke to a very nice lady. Their customer service was excellent btw. I asked her if they test for MG/MS and she said they did. But couldn't remember for sure so she put me on hold to go ask one of the men who worked with the chickens. She came back and told me that he said that their breeding stock *does* test positive for MG and that the man said that all hatcheries have MG and I wasn't going to find any who didn't, or if there were, he hadn't heard of any. (This appears to be mostly true, several big names I emailed or called, either said they didn't test for it, or that they can't say they're MG free) I said thank you, hung up, and made a beeline for the door. Though to their credit, this place has been the only one that admitted having breeding stock with it, even though it's obvious they aren't the only ones... Now for someone with this in their flock already, that keeps their birds forever (keeps a closed flock), doesn't sell hatching eggs or babies, and enjoys their chickens strictly for eggs and pets - this doesn't really matter. Though medicating and keeping a flock with MG healthy can be rather costly after buying medications randomly throughout their lives and replacing lost birds. Some have differing opinions on MG and it's seriousness. This is not up for debate. This is just so those who had planned on getting chicks from their TSC have the ability to check and see where their chicks are coming from, and make a decision based off that. (make sure to ask, I do not think that one hatchery would be able to ship chicks to all the TSC in the country, of course.) I'm not sure how big an area one hatchery may ship to, but it now may be worth it to you to check into before buying and possibly infecting your own birds. Just a friendly heads up.
