    We are new at raising chickens, and we have 10 cornish x. We started them on Co-op's starter/grower, and this past week changed them to the layer crumbles, because they didnt have a finisher. Does anyone know how long they have to be off the starter/grower before you can butcher them. Or does anyone have any advise on how to finish Cornish x's because they grow so different than the other chickens. They are about 7wks old. Any feeding advice would be great. Thanks

    I finish them with the last of the grower crumbles. [​IMG]

    As long as your grower only contains Amprolium, you can butcher them right off the starter/grower feed.

    Some people feel if they get half corn the last week they taste better. Yours are ready to go probably at 7 weeks though so not to worry, what you have done is fine.

    The active ingredent on the tag has Amprolium and Bacitracin Methylene Disalicylate. So does this one need to be a certain time frame before eating??

    According to
    http://www.fda.gov/cvm/FOI/1657.htm

    It seems 5 days is sufficent... but I didn't take much time reading about it so it might not be right. Just google search the drug name and poultry and maybe that can find you more leads. Keep up with the layer feed for a week and it should be fine.

    The feed I use only has amprol in it for cocci.

    Seems to depend on the concentration it was in your feed. It can be from 0 to 5 days. At 5 ppm in the feed the following was found in a study of broiler chickens.

    Based upon the established no withdrawal times for monensin and bacitracin methylene disalicylate, no residues were above tolerances in any tissues from these broiler chickens. The data support no withdrawal for the bacitracin methylene disalicylate/monensin combination.

    I feed only unmedicated feeds and add milk powder if needed, either due to wet damp weather or if I see symptoms, just so I don't have to worry on residues or resistance.

    Anyway your layer for a week should have this handled.​
