I personally only noticed 3 or 4 new breeds compared to last year. The black and red broilers, blue stars and brown stars (maybe).
I've been daydreaming over Ideal's website for years.
I agree that Blue Stars are fairly new, as are Olive Eggers, although Olive Eggers were there last year.
For several years, they've had Gold Sexlinks, Red Sexlinks, and Brown Sexlinks-- those all seem to be renamed as "Stars" instead of Sexlinks this year, but are otherwise not new.
I see that Norwegian Jaerhons are back. They were there in the past, missing for part of last year, now present again.
I don't pay must attention to the Broilers, so I'm not sure how recently the black and red ones were added.
I don't look at the Crested breeds very often, but I think they've added some new Polish colors over the years (red, black crested white, white crested blue).
Mostly, I see Ideal as having dropped many breeds that I was wishing to buy but they were gone by the time I would have been able to get them.
White & tinted eggs: I remember Spitzhaubens, 2 colors of Kraienkoppes, 2 colors of Cubalayas, and at least 5 colors of Hamburgs.
Brown eggs: I remember Red Chanteclers. I'm not sure whether any others are missing from this section.
Bantams, clean legs: I remember Rhode Island Red, Buff Orpington, Barred Rock, Black Sumatra, other colors of Cornish Bantams (Spangled and I think others), other colors of Old English Game Bantams (I bought Millie Fleur and Cream Buttercup colors, but I'm sure they have dropped more than just those two colors). A decade ago, they also had quite a few colors of Dutch bantams, and I'm not sure when those dropped off the list.
I don't like feathered feet, so I don't know what may be missing or added there.
