I have a small flock if 7 chickens 6 pulleys and one roo........ Two started laying at 21 wks they are now 26 wks ( light brahma and RIR) my other 2 brahmas are now 26 wks and I believe have started laying caught the smallest today laying then found her egg in the pen!! But here is my confusion I have a 9 month old bug Orpington who was a later when I got her but from what I saw hasn't started back up again I also have a 15 wk old silver laced ..... I got 4 eggs today for the first time only one was significantly bigger then the rest this is the 3rd time this wk I got one this size I'm unsure if it's the brahma or the buff please help ? I can't figure it out ?
