im brand new at this and something horrible just happened. i have three pullets. they are about 9 weeks old and just went to live outside full time. i had the nesting box blocked off and when i went out to check the girls this morning one of them had gotten her head under the board i was using. i have no idea how she could have done it. she doesnt seem to be able to move. there may be blood on her chest but im afraid to jostle her. she is just opening and closing her little beak and there is white milky stuff in her mouth. its a sunday and my vet is closed, help!
