Most of the girls are a about 2 and about five of them are older and probably don't lay much anymore... The most eggs we have gotten is 12 in a day but in the last 3 days we got 2 then 4 and then nothing today. No changes, they are fenced into 1 acre and sometimes we let them totally free range. Layer pellets, scratch, water... 15 nesting boxes ... I have scoured the pen daily and no eggs, no broken eggs in the bottom of the nesting boxes. We use straw in the boxes and clean the coop 10x8 every other week. The weather has been in the 70's in the day and 50;s at night-we are in WA state. We have a Border Collie who gets along with them great (they go into his dog house with him in fact) so because of the dog we don't have any predators and nobody looks hurt. We had a large group of chickens before and they almost all layed everyday but these girls just never seemed to kick into gear, we got them as babies at the feed store. RIR, Silkies Barred Rock Americanas Polish and a couple Banties(I know I am spelling these wrong) HELP what is wrong with these girls... are they duds? ha ha
