My blaziken had just laid eggs and she has been aggressive towards every pokemon around, including her mate. So far I’m the only one in general she allows near her eggs and while I can understand her behavior and was even prepared for it, this is a bit too much. Is there any way to make her feel less on edge?

Sometimes, a blaziken will grow more comfortable and at-ease if you give her treats before her mate approaches, and other times, she may grow more comfortable if you show her that she can trust others around her eggs with your usual daily care. (That means cleaning her nest, refilling her food and water supplies, getting her to exercise daily, and checking on the temperature of her eggs.)

However, it’s also possible that there’s very likely little that you can do until her brood hatches. Remember, blaziken are one of the few bird-like pokémon that don’t normally have “shifts” when it comes to incubating the eggs. That is to say, the hen lays the egg and incubates them; the mate has very little involvement in them after fertilization. It’s very likely that your hen is attempting to drive away what she perceives as a clingy mate—or, perhaps, a threat to her brood (as a male blaziken can get rather aggressive, even to his own offspring).

For that reason, at most, I would advise just keeping an eye on the hen and ensuring that the hatching goes smoothly—and, of course, that the hen doesn’t do too much damage to her mate.
