So if I were to stick with a grower feed for them and supplement calcium would it have too much protein in it for fully grown hens (when they are fully grown)? I just don't want to do anything to harm any of them. My roo is going to be around as long as he behaves himself. I'm trying to decide on whether I want to be trimming back spurs or not once he gets them (I can't risk it, I don't heal well with wounds, I have a weak immune system), but if he can't contain his boy behaviors and they get out of control he'll have to go whether by cull or rehome (he's SUPPOSE to be a more docile breed, but he's hatchery stock, so not sure). I can tell when he's ticked, his comb gets purple on it, he shakes his leg, flaps his wings, does some vocal warnings, and moves his head around in this weird motion. He's been in a foul mood today so I try to just do what I need and get out when he's having one of those days.
I don't know what flock raiser or all flock type of feed is. The only ones I've used so far are starter/grower feeds, and the only other I've checked into is the layena/laying feeds.
It's really hard to give them too much protein. Excess protein is easily expelled in their feces. There is no toxic gradual buildup, like there is with calcium. Just make sure it's not medicated feed. Medicated feed is fine for feeding young birds who need the protection against coccidia, but when used exclusively, long term, it can cause thiamine deficiency.
