Thanks everyone. I know these things can happen, and when we set the sheds up, we try to think of everything, like no corners they can get squashed into, no large expanses of water to drown in warm enough, cool enough, but something always happens.
That's why the hatchery always give you a few extras, because they expect a few to die, but its still upsetting, especially like you said CN, she made an improvement, she was even calling out to her sisters who are recovering in the hospital box last night.
But hopefully now, they will be okay, as we have just spent the morning finishing preparations for their move to the BIG house! And they are all down there now. they didn't like being picked up out of the brooder shed, but it didn't take them long to start rushing around the new house and eating and drinking. So they will stay in the big house for a week or so until they get big enough not to be able to squeeze through the netting down there!!! And as some of them are still a bit marked on their tails, I'm taking Poulet's advice of keeping them in the dark with their red light on.
He sent me a comment on my blog to say that the tail pecking could be because my brooder shed has windows, and we have the doors open when it gets too warm for them. He said if they are kept in dim lighting with a red light, everything looks red so they can't see the bits of blood and leave each other alone! And the windows in the big house are painted over, then I open the door when they are eating, as they don't eat so much when its dark!
Brian told me to unpaint the windows before, but Poulet has been in the chook business for many years, as has Munty and others, so I will bow to their superior knowledges!!!!!! No windows!!!!
