    If I got it correctly, it is a #chick 😃 But in general, when you can't tell whether a rock or a chick, then leave it unmarked. When you

    can't tell whether a chick or an adult, then mark it as an adult. Always choose the safer choice .) Thanks for your help, check out the FAQs

    for more details about classifying difficult images if you haven't yet. And keep asking, which is definitely the best way to learn it! 😉

    yshish - on FAQ it says pengs do explosive poo to prevent from acid damage to oil on feathers. but we see lots of pics of poo-sprayed pengs

    who sit there. so maybe its just as important to make it explosive away to get it away from seeping down to egg (CaCO3) and damaging it??

    I think the timing of their molt - right after nesting and getting slattered with poo - is probably a response to the impact of the poo

    on their feathers. The value of nesting together outweighs the poo impact, so they molt after and get new feathers.

    Well that's also true - that poo will damage feathers so moulting after breeding and before winter makes a lot of sense 😃
