I have 18 pullets in the coop. My friend raised them for me and I took them home when they were about 10 weeks old. NOT even thinking TWICE, they were introduced to my older laying hens and have since been on layer feed!!!! I have culled all my older hens since and am only getting 3 eggs every other day. They are all the same age at 25 weeks old. I have a mixed flock: columbian wyandottes, black coppers, speckled sussex, cukoo marans, welsummers... All are very healthy and happy... My question: Are they doomed since I started them on layer so early (I just didn't know that wasn't acceptable until lately!!!! I just recently turned into a crazy chicken lady ) Or are they just SUPER late layers? All the breeds I have should start laying around the 20 week mark. Next time I start pullets I promise they will be on grower until they begin laying... but could someone rest my mind?
