I have 4 Production Reds...only a month-old says breeder. They do spend time outdoors and free-range for an hour or two daily. My local store only had Broiler Starter.... 22% protein My questions are... #1- Can I feed this to my girls til I put them on "Layer Feed"... right now I feed them this 3x daily as I got 50lbs of this stuff and don't want to waste it? #2- Or do I need take get Grower Feed at some point? Also, now while on this Starter Feed which is quite powdery... #3-At what point do I need to provide grit? ***And if it's just way too much protein for them @ 2-3 months age; Could I not just feed them 2x daily as they do forage daily and let them eat what they can in 20 mins or so to limit their feed protein intake and just monitor their weight/health? Thank you for your help!
