Glad to hear all went well. He will learn how to go about it but I would be supervising just in case. Mine have been getting a couple every 2 weeks as a treat and I still supervise. The girls are great but our boy still tries to eat his whole.
Its totally up to you but ours only get them once every 2 weeks as a treat, 2 each, and that's it, nothing else for that day. For all other meals they get a mix of dry food, mince & veges.
I personally wouldn't be feeding just the chicken each day, not a balanced diet for them.
