I have 6 chickens, 4 that are 29 weeks and 2 that are almost 20 weeks. I have a Red and a Black sex link, a Australorp, Silkie and 2 younger mixed breed chickens. The Red sex link started at 19.5 weeks and the Black sex link started at 23 weeks. I've been waiting and waiting for the Australorp and Silkie to start (they are the older ones), but they haven't! The Australorp started squatting several weeks ago, but that's it. Should they be laying? It has been very cold and snowy lately...... Should that two mixed breed girls start soon or do you think they'll take longer??? Here are some pics of them. This pic was taken a couple weeks ago. The one on the left has a pea comb and feathered legs so I think she has Brahma in her and the one on the right has a beard, but no pea comb. Should I expect eggs from them anytime soon? Also they are still only 2/3 the size of the older LF girls, but they are the same size (maybe a little bigger) as the Silkie. Should they be bigger??? I do have a red heat lamp going all night if that changes anything. Thanks for any advice!!! I hope it wasn't too confusing!
