User blog:Melkov/Breeding boost after feeding?

I have a vague impression that the following actions boost the probability of successfully breeding a "special" monster:
 * Feeding some monster to a high level (the more food spent the better)
 * Buying a decoration (for coins only)

The effect works only on the first breeding after feeding/buying, in the same game session (do not log off), and only once in that game session.
