I have a similar situation.
One of our neighbours is a farmer, really nice man, lived with his mother but she passed away end of last year, so he is on his own with a cousin who pops in on him.
Yesterday he arrives with 3 lambs, one 4 days old, one 2 days old and one just born

?, still wet.
He has leukemia and had just come out of hospital and his cousin couldn't cope with the lambing and hes not allowed to go near the sheep.
He was very upset and pleaded with me to take the lambs and do ' right by em '

?
I keep a closed flock so its against my better judgement but l had to help.
Other folk are helping him too, how could you not hes in his 70s !
The 2 younger ones l did both their navels with iodine, he said they all had watery mouth powder at birth and colostrum.
One was really empty, yelling, gave her and the other older one a bottle, took some persuasion.
The little guy however was not looking good. Weak and had no idea how to suck.
Spent hours afternoon and last night coaxing him to suck, too scared to tube , gave him a packet of colostrum to be sure he had some.
Fighting my way through this calamity and looking out the window theres a fire blazing about a mile and a half away in the rough heather land, fire men and police

? So now l am ringing my sister who has a farm to bring her stock box and horse box over in case we need to evacuate ! Finally got the wee man to take a full 200ml by 2am, while watching this fire through the sitting room window, phone in hand ! Had a couple of hrs sleep on the settee inbetween making like a meerkat watching the fire.
All lambs took a bottle this morning, l am relieved and drained.
Have a question....... lve had the lambs in the utility room overnight, keep them warm and easier to feed.
What to put them in a hay shed l have, would they need a heat lamp or now they are feeding would they snuggle up and keep each other warm ? Haven't needed to do anything like this before my girls are pretty self reliant

?
Any input gratefully received. By the way l have no intention of putting them anywhere near my sheep for a long time yet untill lm sure they are 100% no risk to my flocks.
