Does keeping chickens in cages until they are old enough to be turned loose in a coop and run cause them to develop slower ? Our area had ALOT ALOT of rain when revented us from building the coop and run area . QUESTION # 1 : OUR chicks were like 10 - 12 weeks old before we could TURN them LOOSE into their new coop and run . CAN or could this cause slower development ? The seem to all be healthy and happy , BUT according to all the pictures in this forum of breeds and ages , MINE seem so much smaller ... TEENS are on proper feed ( GROWER ) and hens are on laying pellets and GET varity of leftovers , plenty water , ETC. QUESTION #2 . Once the hens start laying , is that the ONLY kind of feed that is required for them ?
