ABOUT THE LAYER FEED As far as that goes i called the company that made the chick started i used, asking that same question when to stop with the chick feed and this is what i was told its very important to feed the layer feed at the right time ,they said i could start feeding it at the time i called , my pullets were like 13 to 14 weeks old, cant remember exactly right now but i switched over to their layer crumbuls that day.! good thing because all of my then australorp pullets started laying at 16 week , right on time with all my other pullets of the years before, so i was also told that this was the most important time for them coming onto this stress of laying eggs & for their entire life time to come , its like all females needing that extra calcium support you dont want to leave young layer at a loss for calcium at that time in their lives , if they dont get it their bodies might take that necessary calcium from their bones , like can happen in young woman , plus calcium is most important to any female to help support the reprotuductive process , so not wanting any young layers developing a prolapse or becoming egg bound i would specifically make sure your young girls had all they need during that most critical time in their life.
the BA & Dels & the road island whites , are wonderful happy sweet funny birds , the isa yes are sex links just another hybrid gonna burn out in 18 months.! exactly..!! and besides sex links do have a lot more problems like prolapse & egg binding, because in there first years they are just egg machines...! very unhealthy for those poor birds to bad they are born that way to live such a life . if you wanted a brown or gold color bird in your flock i would look for ORPS they are sweet beautiful birds ,
