When playing version 0.1.7 on android using blue eggs has only shrunk them down to size A and when scenes play I'm still considered to have breasts. When using blue eggs mixed with wild mellon it said it must be a dud.
I believe the problem is that you're lactating honey because of the eggs, which I don't think you can get rid of. Basically your breast rating isn't 1, but 0+1 with 0 being your base breast rating.
This is correct, though the lactation should wind down after awhile as long as you aren't milked in any scenes or get pregnant again. In the future there will likely be items to stop lactation or to stop lactation from increasing breast size, but not currently.
