Novice taking on ex batts! Help...

I know this may not be a great idea but they're a 'surprise' from my previously reluctant hubbie. I've ALWAYS wanted chooks and now my dog (best in the world God bless her - gentle lurcher) has died  I think he thinks I need something to look after!
Anyway...
Can I put the coop in the shade? It would be on the edge of the wood (north side), sheltered from frosts but never in the sun. It will have a large run attached and I hope to let the little darlins out in the day once they've found their feet (and feathers).

Also can I use wood that's been through the shredder as deep litter on the floor of the coop? With straw on top?

Should I put some heat in the coop as my knitting skills may not be up to little jackets ! If so how warm to set the thermostat? We have an oil filled rad we could plug in.

I really appreciate the wealth of know how and experience on this site!!

if this is your first time at keeping chickens then think carefully about having ex batts , they probably will come to you with hardly any feather so at this time of year yes they will need a nice dry warm coop  {shavings is just as good as straw on floor of coop nothing esle is needed under that } also they will need to be carefully checked each day as some may be very weak on thier legs until they have built up muscle . also the immune system wont be very strong so u may at times need to get them to a vet for antiboitics if any of them become will with any illness { people on here are always here to help with that side of things } .

extra feed an tlc is all they need to become healthy birds oh and also time as it could take them a while to adjust .

p.s u dont need to go plugging anything into the coop to give them heat in the mornings if you go in with them u will be surprised at how warm it gets in there with thier own body heat  .

theres a feed out now thats been designed with ex batts in mind so if you get any just look for the feed an u will know they are getting every thing they need to become strong healthy birds except wormers of course for that you will need flubenvet  the list goes on by the way feel free to ask anything u want .
