I just checked him. He filled up his crop again and finally pooping brown consistantly so I'm going to let him go back to the coop. He was pooping green poop (grassy to start then green grainy looking poop near the end) for a long time with intermittent brown. That is another thing I should have waited for, that is for the poop to be consistantly brown as in passing chicken feed poops.
I noticed he likes to eat clover so he may be back in trouble before long. I'm going to lock them up in the run for a couple days so he will have to eat chicken feed.
Thanks all for the help.
