ok I know this is the same old question. I just bought 7 new hens mostly RIR. Also I have 2 spec Sussix and 2 Ameraucana. Everybody was laying really good, now everybody has went on strike. I did change there diet, the guy i bought the hens from was strickly feeding cracked corn. I am feeding Dumor laying mash. Is the change of diet the culprit or is the new coop and run. Or maybe a combination of both. I have 11 hens and one roo. The coop is 8x12 and the run is 10x32.
