Only the females should have layer and only after they start laying. All flock is probably best. Crumble or mash.Many thanks for your information. Much appreciated.
I have been giving them a mix of starters/youngsters pellets, crushed corn and 'grain' (not sure exactly what grain, but the feed store mixes it all in together). I'll buy some layer feed separately - by this, do you mean the layers pellets or wet mash? Can I give them this food from now on (18 weeks old now)? Please excuse my ignorance but I haven't had these problems before and this is the first time I've had 'porky' birds!
They have a 'Dine-a-chook' feeder which allows them to eat when they want. It's hard to feed Valencia separately. Any ideas?
