How do you know the difference between broad breasted bronze vs the regular bronze. I had 3 (no variety name tags on the bins) from the feed store but something got our tom so now I just have the two hens. They are about 8 mos now and they literally waddle when the walk they are so fat and one gets swollen feet and acts like she has to sit down sometimes. They don't act sick or have any respiratory symptoms they just seem too heavy. If they are the BBB do you have to butcher them like you do the cornish crosses or they will die? Sorry if this is a dumb question, but the only turkeys we've had before were large plain white ones lol.
