Help Protect My Babies For Winter & Vet Costs

Hetty is a broiler chicken and should of been slaughtered for the meat industry between 35-42 days old, she is now safe in her forever home, a week ago I bought Hetty indoors as her breathing did not sound good, she’s been indoors and on antibiotics but nothing has helped, today Sunday 20th October 2019 I took her to see a specialist, they have kept her in to give her the best chance, I’m now worried about the other babies outside as due to such bad weather I have had to book builders to come in Tuesday and build 2 sheds one for the broilers and one for the Ducks, they will also put up tarpaulin where needed and extend the wooden runs they will also put up a metal enclosure to keep the other babies dry in wet weather.... their run at the moment is like a complete muddy bog and we are all struggling to move forward due to costs, pls help me to help them
