Conflict at nest (17 May)

The conflicts at nest are many and at last I'm not sure who is who and what has happened ...I still hope everything is going well ...and the eggs are safe ..The pair of Martins defend their nest ...but I had notice once four ! martins all together inside it ...It was difficult to take photos of these conflicts as they last for short time and most time until to take the camera everything has finished ..But this evening I took those photos ...I think the intruder holds with his legs the head of the other as he is up side down ...
