Sorry about your loss(es).
Mine are 4 weeks old and I am letting them out into a chicken tractor for the day too.
And yes there are addicting.
Also, mine have something weird going on with their feet. It's like how a chicken will peck at a red spot on it's foot and make it bigger and bigger. Except that like half of them have it and I can start to see muscle. I am researching that lots but If I can't figure it out I will make a thread.
Can anyone give me a few links to past threads or articles that might explain this?
Good luck with the rest of yours @MaggieMay'sMom
