Today is an experiment of sorts...
Tribble is in "jail" today, in a dog crate inside the chicken barn, mainly to see how the flock, and specifically, Raven do without him, it's looking good so far, Raven has always been the more rooster-ey of the two, he will find food for the girls, keep watch, the only thing he never got to do is mate, as Tribble would never let him
Raven also looks over the EE pullets like they were his own, heck, with Tribble in jail, the other two laying hens are staying with the flock, whenever Tribble is around, they split up and both stay as far away as possible
Tribble would also never do the "good food is here" cluck, and indeed, whenever Raven did, he'd be the first there to steal it, basically, he was always a jerk, a cute, fuzzy, funny looking jerk but still a jerk
I don't take the putting down of an animal lightly, I have to exhaust other options first, but if the flock is happier without Tribble, then he needs to go away
