We have a new hen in quarantine in the bathroom. Tonight I noticed her poo looks normal but a bit small (apparently my son did not give her enough food today and she ran out, and I was occupied with something else and didn't catch it). Two had a small red spot in each of them, not bloody-looking, but like she had eaten a small bit of something red and it came out the other end. One of those also had a bit of yellow in it, like a bit of dried egg yolk. This hen is not quite egg-age yet. Any ideas?
