Sorry if this is a common question being asked for the millionth time, but I'm kind of too panicked to read through previous posts. I just went out to talk to my girls, and Myrtle (2yr old DLB) just threw up about a table spoon of a clear brownish liquid....(WARNING: kinda gross) that she very quickly re-ate, and so did Prudence (2yr old BBCM). Neither one is/has been acting sickly. Both been laying 5-6 eggs a week, even today. Both their combs are nice and bright red......I'm just baffled and a little worried. Any clues?
