Good morning! I received 3 fluffy chicks via post just 3 days ago and wow! do I have questions that google seems confused about!!! I think the girls are different birthdates, because they are different sizes and features. The barred rock is the oldest, and the 2 rhode island reds are possibly a day or 2 apart. One red seemed to have the beginning of pasty butt but with gentle intervention that was alleviated. Is it safe to assume that if the vent is clear and 'winking' at me, then it's fully operational and I shouldn't be concerned about a little mess in the tail down feathers? And in full disclosure as a newbie, I have to admit that I'm not sure what that dark thing is just south of the vent on 2 of the babies. Is that the umbilicus? I'm sure the 2 little ones with the umbilical dangles would really appreciate it if you could educate me about this so I could leave it alone and stop worrying!! And lastly, are these babies supposed to be so quiet? They really only peep when I am around (you would too if you had a vent!). Otherwise they are really content, eating, drinking, even attempting to perch, bossypants....all kinds of chickie shenanigans. Any help you can give me about chickie butts (what is happening to me??) would be greatly appreciated!!
