Sounds great to me. Whenever I get my knickers in a twist as to whether I'm doing it right, giving to little / too much, I just remind myself about the abundance of very healthy looking chickens that run wild in amongst the shanty towns here and don't get any feed EVER. They are beautiful specimens who have hundreds of very healthy chicks running after them and they look like they love their life! The mind boggles as to what they actually do get to eat sometimes, what with the sanitary facilities not being up to scratch etc...It doesn't bear thinking about.
