The Bulgarian Agency For Food Safety has posted another update on their website on the avian flu outbreak reported yesterday (see Bulgarian Food Safety Agency Reports Avian Flu At Poultry Farm In Dobrich), and we are beginning to get more details from the local press. 
At this point the full subtype has not been announced, although we've seen outbreaks of HPAI H5N8 in this region over the past several months. 
First, we have the following (translated) statement on the Food Safety website:

Not mentioned in either of the two official reports we've seen, but being reported by local media, is that the affected farm is supposedly the largest egg producer in the country, where more than 550,000 birds are housed.

So far, only two barns -  involving about 35,000 birds - are reported to be  affected.  This from TVN News.

Bird flu struck the biggest Bulgarian company for production of eggs

Author: June 15, 2018 Video

Only two weeks after the secondary outbreak of bird flu in the village of Stefanovo in Dobrich kindled a new outbreak.

Is smitten largest enterprise for production of eggs in Bulgaria, which is located in the village Donchevo. It raised 550 000 laying hens, so far struck two warehouses in commodity laying hens. A destruction of 35,000 birds, as hopes of owner Ivan Ivanov have this limit contagion.

He informed the Regional Directorate for Food Safety on Tuesday, but yesterday issued an order for the destruction of dead birds flu, it has not really begun.

The owner rejected versions of deliberately infecting with the aim of favoring by insurance or benefits. According to him, they would not be enough to restore production. The farm bred 350 000 200 000 hens and breeding hens produce around 150 million. Eggs per year. Now gives bread to over 200 families.

The main reason for the emerging country outbreaks of avian ban the EC to vaccinate birds and too little spacing of 200 meters between farms categorically Ivanov. The village people today have not yet been notified.

Mayor Donchevo accidentally found out about the situation of the extraordinary session of Dobrich Municipality yesterday, which ironically was convened for the untimely disclosure of the outbreak in the village Stefanov. Official document is not received. Both epizootic commissions - regional and municipal met behind closed doors.

All commercial establishments were sent letters - eggs infected in the last two weeks, to be harvested by commercial halls and be disposed of in the shops themselves.

Determined is a 3-km protection zone, which includes the villages Bogdanovo, Donchevo and Opanets. The marketing and movement of poultry and wild birds and eggs for breeding.

Experts will monitor poultry farms in the 10-kilometer zone. They will be constantly checked by veterinarians.

Regular readers will recall that just over a year ago H5N8 contaminated poultry products shipped from a single infected turkey farm in the Rostov region of Russia sparked a massive months-long operation to remove potentially tainted products from their food chain.

A few blogs on that incident include:
Rosselkhoznador Investigation Into HPAI Contaminated Meat Distribution & Sale
Rosselkhoznador: HPAI Contaminated Poultry Shipped To At Least 9 Regions Of Russia
Russia: Rosselkhoznadzor Finds More HPAI Contaminated Meat In Retail Stores
The concern then was less about human infection with the H5N8 virus - which has never been documented - and more about preventing the inadvertent spread of the virus to farms or to wild birds in other regions of the country.
And those are essentially the same concerns today in Bulgaria, as orders have gone out to destroy all eggs recently shipped from the afflicted farm.
