Frame number as multiple graphics in beamer

Question

In a presentation made with beamer I'd like to have multiples of a small graphic (Easter egg, duck...) in the bottom right corner, where the number of graphics corresponds to the current frame number. If a frame is split into several slides using overlays, all slides have the same frame number and therefore should have the same number of graphics. The navigation symbols should not be visible. Also, if possible, I'd like to be able to stack the graphics in rows by giving a maximum row length (as an integer), after which a new row above the old one is filled. Is there any way to achieve this?

This is (kind of) a MWE that contains the packages I typically use for presentations in order to check for compatibility.

\documentclass[ngerman,10pt]{beamer}
\mode<presentation>
{ \usetheme{Boadilla}
  \setbeamercovered{transparent}
}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{microtype}
\usepackage{babel}
\usepackage{csquotes}
\usepackage{amsmath}
\usepackage{siunitx}
\usepackage{chemformula}
\beamertemplatenavigationsymbolsempty
\title{Easter Ducks}
\author{Prof.\ van Duck}
\date{\today}
\institute{Duck University}

\begin{document}
\begin{frame}{Frame 1}
\only<1>{Text 1}
\only<2->{Text 2}
\end{frame}

\begin{frame}{Frame 2}
\ch{SO2} \pause \\
\SI{5.3}{\kJ\per\mol}
\end{frame}
\end{document}

Answer 1

Sure. Instead of an egg you may want to put an egg-producing creature.

\documentclass{beamer}
\usepackage{tikzducks}
\addtobeamertemplate{navigation symbols}{}{% https://tex.stackexchange.com/a/137028/121799
    \usebeamerfont{footline}%
    \usebeamercolor[fg]{footline}%
    \hspace{1em}%
    \foreach \X in {1,...,\number\value{page}}
    {\tikz[scale=0.12]{\duck}}
}
\begin{document}
\begin{frame}[t]
\frametitle{First}

\end{frame}

\begin{frame}[t]
\frametitle{Second}

\end{frame}

\begin{frame}[t]
\frametitle{Third}

\end{frame}

\end{document}

Of course you can use \includegraphics{...} instead of \tikz{\duck}.

Here is a version for the updated question. It does not pile up the symbols, though, because there is not enough vertical space (and you are very generous when it comes to load unrelated packages so the compilation time is unnecessarily long which prevented me from playing with many slides where this piling up might make sense).
