I' m planning on goose hunting corn and bean fields where there are large populations of snows, blues and canadas. I have 12 bigfoot canadas, 100 texas rag snows/blues and 25 silhouette snows decoys. Can I be successful using all the decoys in the same spread and if so should the canadas be separate from the snows/blues. Thanks for any info.

Since you have a small amount of Canadas, I would set them in their own small flock to one side. Even with larger spreads, they tend to segregate, so show that in your decoys. Put the bigfoots and silos on the downwind side as those will be seen up close by the birds when they come in.
