You'll struggle to get POL at this time of year in general unless you are after hybrids, the POL birds now will have had extra feed and heat to get them through their late hatch and with rearing prices the way they are a lot wont bother to hatch late as people never seem to want to pay the spring premiums for birds.
I have two barred Wyandotte bantams at £25 the two if you fancy a trip to Towcester!
