I do wildlife rehab and we are in the middle of the crazy baby season well today a group of maybe 2 day old mallards came in their mom was killed as we have over 150 of them the awww cute factor has worn off to the oh my I am tied of cleaning stinky babies well this group got my attention some of the babies are lite yellow with yellow feet now they do have mallard markings in light gray. And they are the same size as the others. Anyone have any guesses as to what they are mixed with? Oh I know everyone wants pictures I will get some I was so tired when I left tonight I forgot to take one and they are on the main site so I will get one up soon.
