I have messaged the lady this morning and she has advised there will be NO INTACT boys unless we want them intact which is great as we don't.
She is having them de-horned and everything before we get them, I am also going to buy a couple of little coats off her too.

We will definitely watch how much they are getting, thanks for that advice.

We have been buying hay off a local farmer to use for chicken bedding, I might get some more and have a block in their room for eating, jumping and sleeping

They can share scraps with the chickens but they will be separated from the grain feeds at night so that shouldn't be an issue.

I like the idea that while they are so little they be in the room where it is warm & safe, as they grow though I will probably allow them to roam around and just use the outside shed at night.

The girls are going to love them, I will have to buy them a collar so we can tether them in some of the unfenced areas and so the girls can take them for walks

I might even talk to DP about running some wire around the trailers, we have 3 trailers down there at the moment and no-where else where they can't be seen or easily accessed.
