Hello 
I have a small flock of 5- 3 welsummer hens, an orpington hen and an orpington roo- in my back garden, and one of my hens, a welsummer, has gone broody and has been sitting on 3 orpington eggs for the past 3 days. I understand that welsummer hens are not known for being the best mothers but I've decided I'll let her have a go anyway. I have a friend close by who is currently hatching eggs in an incubator and is willing to take my chicks into her brooder should my hen prove a useless mother. I have never hatched chicks before so this is all new to me and I'm not sure how I should proceed! I would like to let her hatch her chicks in the main coop with the existing flock, to avoid having to reintroduce her and the chicks at a later date, but the coop is raised (as you can see in the picture) a couple of feet above the ground, and the roosts are also raised, the lowest as about 17 inches high. I'm asuming this would make an unsuitable home for chicks? So I'm planning on putting her in a broody coop with an attached run alongside the existing run (please note that we have now doubled the width of the run, so it is twice the size of that seen in the picture). That way she may still be able to have some interaction with the existing flock. So, should I separate the broody hen and her eggs now, or wait until closer to the due date or until after the chicks have hatched? and how long should I keep her separated for? Until she weans the chicks away from her? or until the chicks are ready to go in with the flock? at what age would the chicks be able to go in with the flock, if at all? Will i need to add some kind of heat to the broody coop? or will my hen provide enough heat for the chicks for the cool uk summer nights?
Thanks in advance! here's some pictures of the existing coop.
