I had some birds that hatched at the end of April, they laid in the following year like gangbusters!
I got some Welsummer bantam pullets that hatched at the end of March, still no eggs, their combs were red but now they are pink. So it may be spring before they will lay! I have to be patient so if they will lay, they will lay at their own time!
Patience is the key, some breeds lay later than others, more so on the breeder, show exhibit birds than hatchery stock.
