I am confounded. I have 4 hens, all different breeds. I believed they were all laying, but either my EE lays 2 eggs every other day or so or I am wrong about a breed. I am adding pics of the birds and today's eggs. They are all about 5 months old.

Isa Brown

Leghorn - dust bath dirty
My EE

My EE - same as chicken above. Thought I could delete the other one.

What I thought was a white Plymouth rock - however when I bought her from TSC she was in the Ameraucana box - could she really be an EE?

Today's eggs. Sorry it's a little washed out. In order from left to right 1. white/leghorn 2. brown/Isa Brown 3. Blue/EE 4. Blue/EE or other white chicken?
