We have 17 chicks total, 5 Araucanas 6 Barred Rock 2 Buff Orpington and 2 Red Star. They're all 15 days old as of today, we have them in our finished basement in a brooder while the chicken coop is being finished. Their brooder has a 3 foot border to keep them "inside" - lately at least two have been able to fly up on the edge of the brooder. I don't want them to get out and somehow get hurt. Isn't this kind of young for them to be able to fly so high already? I was planning on clipping their wings eventually, but it looks like it may have to be sooner than later. Is it safe to clip their wings at such a young age? Thanks for your help!
