We bought our sweet Amber Star at 20 weeks (along with some 'sisters' of varying ages) and I was told to expect her to start laying at around 25 weeks. She still hasn't laid an egg. We're feeding her layers meal and scraps, they all have the roam of our quite large back yard (searched all around, no eggs) and have a coop with nesting boxes visible and near. Is there anything that could be preventing her starting to lay? They seem to be happy social birds, not stressed and no reason to be. We also have an Ameraucana who is 29 weeks (although I have read these can be late developers) and a Black Sex Link who is 29 weeks, a Production Red and a Silkie who are both 25 weeks. No eggs from any of them. Any help or pointers? Anything we're doing wrong possibly or not doing at all? Thanks in advance!
