I think my Hogs have scared my hens...?

3 weeks ago my 25 hens started laying on average 16 eggs a day. This was a major improvement, since for the last 3 months they were laying only 2 a day. They were molting and they were getting used to their new place on our farm and their new coop.

Last week i picked up 2 guinea Hogs. They are about 40 lbs each. By magic they are able to get inside the chicken coop. I dont keep food in the coop (since i feed the chickens once a day at night after i close the coop up for the evening).

I just noticed the hohs are getting into the coop and just sniffing around. But now the egg production has slowed to just 1 egg a day....
what dhould i do?
Ideas...raise the chicken door high so the chickens will have to jump inside.
...put an electric fence snout high so the pigs dont try to get in...
...just deal with it until the pigs get too fat to fit through the tinny hole. It is only about 7×8 inches.
Please help.
