When do i change from growing mash to laying mash for my 22 RIR. they are "singing" and making round nest like in the hay in the coop even tho i have nesting boxes. the 2 roo's, Alice-who turned out to be Andrew and General manchu are both doing their job, they are 14 weeks old, so i don't know what age they start laying, i just know we would like to see some eggs.

Lay between 18-24 weeks. Some change feed at first egg
or around 18th week - up to you.
(your post reads like you are expecting eggs from Roos-LOL)

They should start laying between 18-26 weeks or so. I would start feeding laying mash a 20 weeks or the first egg, which ever comes first.

not looking for eggs from my roos, i just meant they were acting like the usual male around a lot of pretty girls, strutting around and showing off.
