My hens love to set. we have one that will set for 5 months at a time. The other day i had a hen that was on the verge of death because she had been setting so long. she's okay now though. i brought her inside and gave her food and water. they get dehydrated from setting so long. i have tried everything. they always go back to their nest. we have about 5 setting at the moment. we don't need any more chickens. we have so many! please help!
