CCL stands for cream crested legbar! :D #3 could be a marans cross, that does sound a little sketchy but he could have also been misinformed or not insanely experienced ( or egg colors are too similar?) So I don't know if it was malicious or cheating you or anything, the birds are big, healthy...
1. Are you sure those are the only 3 breeds you got? He doesn't quite seem like any in honesty... Hmm
2. Swedish Flower
3. Looks like. CCL but he's got feathered legs, so I guess CCL mix or not a good CCL line? Another hmm
4. Cream Crested Legbar
5. Cream Crested Legbar
6/7. What hatchery did...
