Retired in 2005, breeding Araucana chickens.   After the rooster has mated with a hen the sperm packet is good for about 10 days. Unlike most creatures the birds do not need fertilizing each time, for each egg. The sâ¦perm is stored in the cloaca of the hen for up to 10 days and then needs replenishing.

The lamellipodium (plural lamellipodia) (from Latin Lamina - thin sheet, pod - foot) is a cytoskeletal protein actin projection on the leading edge of the cell.It contains a quasi-two-dimensional actin mesh; the whole structure propels the cell across a substrate (Alberts, et al., 2002).Within the lamellipodia are ribs of actin called microspikes, which, when they spread beyond the lamellipodium frontier, are called filopodia (Small, et al., 2002).rp2/3 complexes are present at microfilament-microfilament junctions in lamellipodia, and help create the actin meshwork. Arp 2/3 can only join onto previously existing microfilaments, but once bound it creates a site for the extension of new microfilaments, which creates branching (Weed, et al., 2000).
