Your not the only one Moll,spoke to a pal yesterday and he's had nothing to sticks this year,all chicks have died on him with different types of birds.My year has leveled out a bit and although i lost a chick yesterday(a greenie) it was a very small chick and didn't expect it to make if i'm honest the other nests i have are doing ok,if your cock is feeding them ok up till now he should finish them off without to much problem i should think.I've found once the cocks start they do stick at the task,well my lot seem to anyway.Good luck.
