My Flock of 8 male rosters don't eat anything but leftover food

[VPerfeito]

Hello. 3 month ago I received 1/2 month 8 red bald neck roosters. When they arrived I fed them crushed corn and they loved it. They eat it like monsters. Then they got bigger and I start feeding them with corn and some mixed chicken feed. Besides this, they had grass/ cabbages / and leftover food. They didn't like the change but they got accustomed to it. Now, for more than a month, they don't eat anything but leftovers. They don't eat the corn, chicken feed, the crushed corn or even starter chicken feed. They don't eat anything besides leftover. However, they look very healthy but they are thin and hungry. When they see me with a bucket they run like crazy thinking ists leftovers. When they see that it isn't they turn around. They do no free-range which mean they don't eat anything from the soil. I have even tried to make a paste with water, cabbages, crushed corn, chicken feed and I didn't get a single peck. Since they don't eat, I throw this mixture to baby chicken and the adult hen flock and they just loved it. I have no more ideas, don't know what to do. By this age they should be much much bigger than they really are. Thank you.
P.S: The corn I give them is whole but a small grain

PS: They are not filling on treats.... I visit them every 3 days (i don't leave near) and they eat the leftovers I collected during those 3 days at home. When I arrived every corn I left there 3 days ago is still there

Why not stop all food except chicken feed? Sounds like they may be filling up on treats, but are not get the nutrition they need.

Malnourished, and very hungry! If there's a balanced grower or all flock feed available, offer that and nothing else. If you actually have to make your own feed, look up what goes into a balanced ration for them.

The thing is...they dont eat it

Corn isn't a complete diet for them either! They are not getting a complete diet, which needs to change.

I agree with the other commenters, try leaving them with nothing but a good grower feed and grit. Once they don't have a choice, they'll eat it.

they also eat chiken feed..but yes i agree. I have never had troubles with this feed system

They need a complete diet. Sure it may not hurt them to eat treats all the time, but if something happened like they got sick or injured they wouldn’t be able to heal themselves. I would feed a Flock Raiser, All flock, or grower/finisher to them. They need protein leftovers don’t necessarily give them.

Would Portugal even have feed like that for sale?
