Who did my egg come from?

[Matejka]

I Have a black Australorp cockerel-that counts him out. The rest are pullets-ALL 6 are 17 WEEKS OLD. 2 new hampsshire, a black sex link, a black Australorp, and 2 gamenYesterday, all 7 in pen all day, about noon I heard "the egg song" and about 1 went out to coop and found 2 small pinkish brown eggs. Today, all 7 out free ranging, the 2 game are wild and never ever stay with the flock-they go their own way. Checked coop at noon-nothing. Since noon, the flock of 5 has been in the yard, no one ever went to coop at 5 I checked coop, 1 pinkish brown egg-small. I thought games laid white eggs. Who is the guilty girls? Any ideas how to figure it out? Pic is next to a large egg for comparison. Also, eggs are getting slightly darker.

All 4 girls lay brown eggs. I cant tell my girls egg apart. Just keep an eye on the coop. One of them had to go in there lol.

I strongly feel it's the 2 wild games. Thanks for the insight

I dont have any of those so I have no idea what their eggs would look like sorry. Good luck with figuring out who the culprit is!!! The first egg is so exciting
