I am new to the forum & a new chicken mom too. I have read & learned a lot from these forums & now find a need to post a question for help. I have a hen who is 10-12 weeks old I think, best I can calculate since I got her from Rural King on sale because they said they were older & they needed them gone & simply told me they were anywhere from 1 to several weeks old. Yesterday, 5-22-17, she started making a constant slow cluck type sound & I am unsure if it is normal or something wrong with her. None of the other chickens are doing it & she never did it prior to yesterday & today. I tried videoing her doing it. She is drinking, eating, & pooing all normal. No discharge from eyes or nostrils. On medicated chicken starter, is not free range due to too many wild animals that could harm them. I give them electrolytes & probiotics in their water. Otherwise acting fine. Any help? I have never owned chickens or even been around chickens until these girls. I started with 12 Rhode Island Reds & ISA Browns, & then loved them so much went & got 12 more 2 weeks later. But I am totally knew to owning chickens & learning as I go, worried for my girl. I appreciate any advice, opinions, or help. Thanks.
