These were ones the farmer hatchd on her farm and never purchased. From what I gather I now believe these are all Barnyard Mixes. Maybe all original were just those three breeds, but the lines have been mixed.
Yes, in that case they would be Barnyard Mixes.
Given what breeds the farmer started with, they are probably all good layers, so a nice flock to start with!
So Lenny isnt a leghorn. Well I guess I will have to be content with them as they are. Any guess for what Lenny could be? In googling around, I am confident Jerry is definitely "mostly" ISA. But now doubting that too.
The original three breeds were White Leghorn, ISA Brown, and Rhode Island Red.
ISA Brown is actually a hybrid, with a Rhode Island Red father and a Rhode Island White mother, so it can pass on any of the genes from either of those breeds.
The white ones (Lenny & Abby) most likely have some Leghorn but some of the other kinds too.
Jerry could have two ISA Brown parents, or one ISA Brown and one Rhode Island Red parent. I'm guessing he does not have Leghorn, but I cannot be positive.
Macy has some ISA Brown in her (white markings). She may have Rhode Island Red as well, but any Leghorn would be a few generations back.
Cleo and Margot most likely have Rhode Island Red, with perhaps some ISA Brown as well. Any Leghorn is a few generations ago for these two.
I think the other hens, Bella, Dove, Faye, and Lola, have some Leghorn in them, but it's a grandparent or further back, not a parent. The black and the blue probably come from Leghorns, but it takes at least two generations to start seeing those colors, because of how the white genetics work in this case.
