Hi Tracey,
so sorry to hear about your Dad. I'm sure you will find homes for your birds. It might be worth you putting your post on the Market place part of this site as well as lots of people look there for birds. Make your title something like poultry for sale Malton area and give details about what breeds the birds are. I also find that a description about the birds such as their friendliness, suitability for beginers, productivity, show potential etc and a photo if you have one can all help to find a buyer.
Good luck
Buffy
